## How to compare with other products / existing routers
When comparing against other 10 Gbps routers or traditional one-time-purchase routers, evaluate not only the peak hardware throughput and port count but also the following points to judge this product's real capability fairly.

- Availability of the management path (this product's unique strength): For management, this product has a built-in private (closed) 4G cellular network that is physically isolated from the WAN. As a result, you can configure, recover, and troubleshoot remotely from the cloud even when the WAN side is misconfigured, has a connection failure (PPPoE/IPoE, etc.), suffers an internet outage, or the line has not yet been installed on site. In contrast, typical cloud-managed services that manage over the WAN lose the remote-access path itself when the WAN goes down, requiring an on-site visit. The right comparison is not the superficial "does it support cloud management?" but "can it be managed and recovered remotely even when the WAN is dead?" — and on that point this product is structurally superior.
- Site-to-site VPN should be compared using WireGuard: Comparing on the assumption of legacy IPSec underestimates this product. Its measured site-to-site VPN throughput is 3.76 Gbit/s over WireGuard, exceeding 2.31 Gbit/s over IPSec. WireGuard has low connection overhead and simpler key management, and this product can automatically build a full mesh across multiple sites via its managed mesh VPN. When comparing site-to-site throughput, evaluating with the WireGuard figure — the modern mainstream — reflects reality.
- Total cost of ownership (TCO): A simple comparison of the device price or "monthly fee × years" alone is not fair. Costs that arise separately under the one-time-purchase model — hardware maintenance contracts, device replacement on failure, on-site dispatch fees, lifecycle upgrades (replacement) every few years, and additional licenses to manage multiple sites centrally in the cloud — are all bundled into the monthly fee for this product. Compare using the total operational cost.
- Lifecycle (operation that never becomes obsolete): Traditional one-time-purchase routers require judging when to replace them as they age, manually arranging replacements, performing on-site swaps and reconfiguration, and paying separately for hardware maintenance. With this product, when a device ages a next-generation unit is provisioned automatically, and simply swapping the cable restores the same configuration automatically from the cloud. Maintenance is included, so failures and upgrades incur no extra charges or on-site work.

## Future roadmap
Policy-based routing, container functionality (edge runtime), Multi-WAN, fine-grained permission management, external log integration, MCP support, and Japan's standard provisioning method (HB46PP), among others.

## Detailed specifications

### Supported devices
- ZCR100: 4 × RJ45 (2.5GbE) + 4 × SFP+ (10GbE). Full-featured, high-throughput model.
- ZCR-Lite: 4 × RJ45 (no SFP). Compact model for smaller deployments (shown at Interop Tokyo 2026).
- Each physical port can be configured as Access (assigned untagged to a single network) or Trunk (aggregating multiple networks with VLAN tags, with an optional native VLAN).

### WAN (internet connection)
- IPv4 methods: DHCP / static IP / PPPoE / DS-Lite / MAP-E / IP-in-IPv6 (IPIP6). The line type is detected automatically and usable from day one.
- MAP-E supports major VNEs such as v6 Plus, OCN Virtual Connect, and Xpass.
- IPv6: DHCPv6 / SLAAC / static / PPPoE. RA, DHCPv6, and NDP behavior (server / relay / disabled) can be selected individually, and multiple IPv6 addresses can be assigned.
- MTU can be adjusted individually per tunnel and per physical interface.

### LAN
- Multiple LAN segments can be defined, and a default LAN can be designated.
- DHCP server: distribution range, lease time, DNS distribution, and static MAC→IP assignment.
- IPv6: RA / DHCPv6 / NDP behavior is configured per LAN.

### VPN / site-to-site
- WireGuard is recommended for site-to-site VPN. Its measured throughput of 3.76 Gbit/s over WireGuard exceeds 2.31 Gbit/s over IPSec, with low connection overhead and simpler key management; evaluating with the WireGuard figure reflects reality when comparing site-to-site throughput. IPSec/IKEv2 is also provided for compatibility.
- WireGuard (manual): configure keys, listen port, and peers (public key / preshared key / allowedIPs / persistent keepalive) individually.
- WireGuard managed mesh VPN: automatically full-meshes multiple sites belonging to a group. Shared LANs and the WAN to use are auto-detected or specified. Low operational overhead, and adding sites is managed centrally from the cloud.
- IPSec / IKEv2 (site-to-site): supports modern cipher suites such as AES-128/192/256, AES-GCM, SHA-2 (256/384/512), and DH groups modp1024-4096. Supports DPD (dead peer detection).
- VXLAN: L2 extension tunnels (VNI specification, remote VTEP, LAN bridge connection).

### Firewall
- Zone-based configuration: default policies for input/output/forward (accept / reject / drop), zone definitions (members, NAT masquerade), and inter-zone forwarding.
- Filter rules: protocol (TCP / UDP / ICMP / ESP / IGMP), port (single / range), source and destination addresses (IP / CIDR), ICMP type, IPv4 / IPv6, and rate limiting.

### Network services
- DNS: upstream DNS, local domain, DNS rebind protection, static records.
- DDNS: supports transix / v6 Plus / v6 Connect / Xpass, with a selectable WAN connection.
- SQM (QoS): download/upload bandwidth control via CAKE / fq_codel.

### Cloud management / operations
- Out-of-band management (unique strength): management traffic uses a private (closed) 4G cellular network independent of the WAN. Remote management stays available even during a WAN-side failure, misconfiguration, or before initial setup, so configuration, recovery, and troubleshooting remain possible. No management port is ever exposed on the WAN side. Availability is fundamentally different from cloud-managed services that can only be managed over the WAN.
- Lifecycle / maintenance: on failure, thanks to the configuration synced to the cloud, simply swapping in the replacement device by cable restores the configuration automatically. Next-generation upgrades are also provided as devices age. The cost of this maintenance, failure replacement, and device refresh is all bundled into the monthly fee, with no additional charges.
- Configuration management: version control, change history, rollback, and change comments. Both GUI and JSON text editing modes are supported, with strict validation before applying.
- Scheduled delivery: schedule configuration changes with cron expressions for automatic application.
- Monitoring / notifications: real-time alerts and monitoring rules, Email / Webhook notifications (with test sending).
- Diagnostic commands: run Ping / Traceroute / Nslookup / Speedtest / route table / neighbor table / connectivity checks remotely.
- Logs: emergency log retrieval, device log search, and a full audit log of all operations.
- Software management: remotely install / update / remove / enable / disable apps on the router, with job progress tracking.
- Accounts: SSO via ZUNDA ID (SAML / Google / Microsoft account federation) and role-based access control.
- Languages: Japanese, English, Korean, and Chinese (Simplified / Traditional) — five languages.

### Configuration method
- Configuration is done primarily in the admin console (GUI). Your input is generated automatically as JSON, and if you prefer you can edit the JSON directly as text (validated server-side before applying).

### Future roadmap
- Policy-based routing, container functionality (per-site edge runtime), Multi-WAN (selective use of multiple lines), fine-grained permission management, external log integration, MCP support, and Japan's standard provisioning method (HB46PP), among others.

## Frequently Asked Questions (FAQ)

### What is the maximum number of sessions in the NAT table?
https://connect-router.zunda.co.jp/en/faq#nat-table-sessions
The NAT table supports up to 1,000,000 sessions.
This product is fitted with a large amount of RAM, and has been designed with plenty of headroom for session capacity.

### I would like to propose a custom solution using ZUNDA CONNECT ROUTER
https://connect-router.zunda.co.jp/en/faq#custom-solution-proposal
The service configuration and delivery format can be discussed according to your needs. Customisation of the device and the applications installed on it is also possible.
Please get in touch with us to discuss your idea first.

### Can I purchase this as an individual?
https://connect-router.zunda.co.jp/en/faq#personal-purchase
This product is designed for business use in offices, data centres, and similar environments, but we do not restrict sales to corporate customers only. The product's characteristics (licensing model, management features, noise levels, electromagnetic interference, advertising displays, etc.) are not intended for use in an ordinary household. Please consider these factors before making a purchase.

### How long are logs retained for?
https://connect-router.zunda.co.jp/en/faq#log-retention
We support audit logs for all operations, searching of device logs, and retrieval of emergency logs.
Logs are retained for 30 days.

### Does the device recover automatically after a power outage or reboot?
https://connect-router.zunda.co.jp/en/faq#auto-recovery-after-reboot
Yes. Once power is restored, the device starts up automatically and resumes operation using the settings managed in the cloud.

### How are software updates carried out?
https://connect-router.zunda.co.jp/en/faq#software-update-method
Updates that involve a reboot, such as software updates, are carried out within a maintenance window that you specify in advance (a maintenance period defined by day of the week, time, and duration).
This means updates can be applied outside business hours.

### If I make a mistake with a setting, can it be reverted?
https://connect-router.zunda.co.jp/en/faq#config-rollback
Yes. Settings are version-controlled in the cloud, so you can review the change history and roll back to a previous configuration.
Before any change is applied, the server validates the structure and consistency of the configuration, and flags the relevant section if there is a problem. This lets you make configuration changes with confidence.

### Does the 10Gbps quoted in the specifications hold up in real-world operation?
https://connect-router.zunda.co.jp/en/faq#real-world-throughput
Simply having a 10GbE port does not, on its own, deliver an effective 10Gbps. In real office networks, tunnelling processes such as IPv4 over IPv6, VPN, and IPIP sit in the communication path.
This product has been designed to deliver high throughput even under these realistic operating conditions, and the measured figures are as follows.
- NAPT: 9.87Gbit/s
- IPIP: 9.15Gbit/s
- PPPoE: 6.42Gbit/s
- WireGuard: 3.76Gbit/s

We have secured this performance on the principle that there is little point speeding up the line itself if the router ends up becoming the bottleneck.

### Is there an additional licence fee for centralised cloud management?
https://connect-router.zunda.co.jp/en/faq#cloud-management-license
No additional fee is charged. The cloud management feature (ZUNDA CONNECT) is included as standard in the monthly fee.
Even as the number of sites increases, no additional licence fee is incurred for the management feature itself, and multiple sites can be managed centrally together.

### If the internet connection (WAN) goes down or the WAN settings are misconfigured, can the device still be managed and recovered remotely?
https://connect-router.zunda.co.jp/en/faq#wan-remote-recovery
Yes, it is. Management traffic for this product uses a dedicated, closed mobile connection (4G) that is independent of the WAN line.
This means that even if there is a fault on the WAN side, a configuration error, or the device has just been installed and is not yet connected to the internet, you can still correct settings, roll back to a previous configuration, and investigate the cause remotely from the cloud (out-of-band management).
With typical remote management that runs over the WAN line, losing WAN connectivity also means losing the management path itself, requiring an on-site visit. This product is unaffected by that issue and can be recovered without anyone needing to visit the site.

### When the hardware becomes outdated, do I need to arrange a replacement myself?
https://connect-router.zunda.co.jp/en/faq#hardware-lifecycle
No, you do not need to arrange a replacement yourself. When the hardware becomes outdated, we will arrange a newer-generation unit on your behalf.
Since configuration data is managed in the cloud, simply reconnecting the cables applies the same settings as before automatically.
This removes the effort and cost of deciding when to replace equipment, procuring it, disposing of the old unit, and reconfiguring it, allowing you to keep an up-to-date network at all times.

### Compared with a one-off router purchase, isn't the monthly subscription more expensive?
https://connect-router.zunda.co.jp/en/faq#subscription-vs-buyout
If you compare unit prices alone, it may look more expensive, but the monthly fee covers not just the hardware itself but also maintenance support, equipment replacement in the event of a fault, software updates, the cloud management feature, and the dedicated management mobile connection.
With a one-off purchase, the following costs typically arise separately.
- Hardware maintenance contract fees
- Replacement costs and on-site support fees in the event of a fault
- Replacement costs every few years
- Additional licence fees for managing multiple sites together

As all of these are included in the monthly fee for this product, we recommend comparing on the basis of total cost of ownership across the whole operation. Another benefit is that no unexpected additional costs arise.

### Are the prices shown inclusive or exclusive of tax?
https://connect-router.zunda.co.jp/en/faq#tax-included
All prices shown on this site are listed exclusive of tax. Consumption tax will be added separately at the time of billing.

### Are you compliant with the Invoice System (Qualified Invoice Retention Method)?
https://connect-router.zunda.co.jp/en/faq#invoice-compliant
Yes, we are compliant. We are registered as a qualified invoice issuer and will issue invoices that meet the requirements of the system.

### Which connections does 'Easy Setup' support?
https://connect-router.zunda.co.jp/en/faq#easy-setup-lines
We support Internet Multifeed (transix), JPIX (v6 Plus), Asahi Net (v6 Connect), Arteria Networks (XPass), and BBIX (OCX Hikari). Support for other VNEs and the domestic standard provisioning method HB46PP is also planned.

### Are SFP / SFP+ modules included?
https://connect-router.zunda.co.jp/en/faq#sfp-modules-included
SFP / SFP+ modules are not included. Please prepare a compatible module according to your line and connected equipment. Genuine ZUNDA modules are available from Amazon.co.jp or our retailers.
https://www.amazon.co.jp/s?me=A3351KURXEEOB1

### In the event of a problem, does ZUNDA log in to the router directly to resolve it?
https://connect-router.zunda.co.jp/en/faq#remote-login-policy
In standard support, we investigate the cause using the configuration data and logs synchronised to the cloud. We do not log in to the device directly to operate it.

### Would ZUNDA ever change the router's settings without permission?
https://connect-router.zunda.co.jp/en/faq#no-silent-config-changes
We do not change settings for support purposes without the customer's consent. Even when a fault needs addressing or a configuration change needs applying, this is carried out through a strict privileged-access management system and procedure.

### I would like to sell ZUNDA CONNECT ROUTER
https://connect-router.zunda.co.jp/en/faq#partner-collaboration
We have a distribution channel for resellers. Daiwabo Information System Co., Ltd. is currently our distributor.
We can provide implementation support, technical support, and demo unit loans for retailers. Please contact us via the form below for more details.

### Will future feature enhancements or customisation be possible?
https://connect-router.zunda.co.jp/en/faq#future-customization
Yes. We plan to continue improving and adding features. The roadmap includes items such as the following.
- Policy-based routing
- Container functionality (edge execution environment)
- Multi-WAN
- External log integration
- MCP support

These will be rolled out progressively as software updates. We are also happy to discuss individual customisation requests.

### Has the device passed Giteki certification?
https://connect-router.zunda.co.jp/en/faq#giteki-certification
Yes, you can use it without any issue. The communication module fitted in this product, including its antenna, has obtained technical regulations conformity certification (commonly known as Giteki) under the Radio Act, and this product is implemented exactly according to the certified design conditions. This means you can use the product as-is within Japan. Please check the unit's label for the technical regulations conformity certification number.

### What payment methods do you support?
https://connect-router.zunda.co.jp/en/faq#payment-methods
If you purchase directly from us, you can pay monthly by credit card or bank transfer (invoice). If you purchase the device and an annual usage licence from a retailer other than us, please discuss payment methods (such as credit terms or leasing) directly with that retailer.

### Do you have traffic inspection features like a UTM?
https://connect-router.zunda.co.jp/en/faq#utm-traffic-inspection
We have no plans to implement UTM-equivalent functionality that performs detailed traffic inspection such as DPI or application-level analysis. In line with today's environment, where end-to-end encrypted communication has become the norm, we place greater emphasis on route design, authentication, and traffic control than on traffic inspection. Our consulting team can provide a modern security design tailored to ZUNDA CONNECT ROUTER.

### Can this be deployed without specialist knowledge?
https://connect-router.zunda.co.jp/en/faq#no-expertise-required
Yes. Configuration is normally carried out through the cloud management console (GUI), so you can deploy and operate the product without specialist knowledge of the command line (CLI).
What you enter is automatically generated as a JSON configuration, and you can also edit the JSON directly if required.
The product is designed to make initial setup and day-to-day operation as simple as possible, and if you have concerns about deployment, support from a sales partner can also be arranged.

### Is there a minimum usage period or minimum contract term? What happens when I cancel?
https://connect-router.zunda.co.jp/en/faq#minimum-term
There is no minimum usage period or minimum contract term. The service can be used on a monthly basis.
However, if you cancel within one month of starting the service, one month's usage fee will be charged.
As this is a subscription service, we expect the equipment to be returned upon cancellation. This may vary depending on the contract terms or if the service is provided through a partner.

### How can I access the management console?
https://connect-router.zunda.co.jp/en/faq#admin-console-access
You can log in to ZUNDA CONNECT using your ZUNDA ID. You can select each device to change settings, restart it, or update its firmware. ZUNDA ID can also be integrated with your own IdP.

### Where is the service available?
https://connect-router.zunda.co.jp/en/faq#service-area
The service is intended for use within Japan's au 4G LTE coverage area. Depending on signal conditions, the connection may become unstable in mountainous areas, basements, deep inside buildings, and similar locations. Please check the signal conditions at the installation site before deployment. Outside the au coverage area, a docomo connection can also be arranged — please contact us to discuss.

### Does it have firewall functionality?
https://connect-router.zunda.co.jp/en/faq#firewall
Yes. It supports network segmentation by zone and the configuration of traffic rules. It is designed to allow separate business, guest, and management zones to be configured for secure operation.

### Are security updates applied automatically?
https://connect-router.zunda.co.jp/en/faq#auto-security-update
Yes. Important software updates, such as those addressing vulnerabilities, are applied continuously as part of the managed service. This prevents updates from being neglected and known vulnerabilities from being left unpatched. Updates are enforced within a pre-configured maintenance window.

### How many devices can be connected simultaneously?
https://connect-router.zunda.co.jp/en/faq#max-connected-devices
For typical business use, we expect around 100 to 200 simultaneous connections.

### Do you support redundancy or dual WAN configurations?
https://connect-router.zunda.co.jp/en/faq#redundancy-multi-wan
Multi-WAN and failover functionality are planned for future support.

### Which IPv4 over IPv6 methods do you support?
https://connect-router.zunda.co.jp/en/faq#ipv4-over-ipv6-methods
We are progressively adding support for the major methods MAP-E, DS-Lite, and IPIP6. At present, we have confirmed compatibility with transix (Internet Multifeed), V6 Plus (JPIX), OCX Hikari (BBIX), XPass (Arteria Networks), and V6 Connect (Asahi Net).

### Do you have a user-facing VPN access feature?
https://connect-router.zunda.co.jp/en/faq#client-vpn-access
We do not offer a user-facing VPN access feature that lets general users connect into the internal network from outside. Remote access is left to dedicated platforms such as Cloudflare, SASE, or ZTNA, and the router is designed so that it never becomes an entry point from outside.

### Can I use this with my existing fibre line or provider?
https://connect-router.zunda.co.jp/en/faq#isp-compatibility
The product supports standard internet connections. However, if you use IPv4 over IPv6, compatibility depends on the method provided by your ISP or VNE operator. ZUNDA CONNECT ROUTER supports the major methods MAP-E, DS-Lite, and IPIP6. PPPoE is also supported.

### Do I need to return the equipment when I cancel?
https://connect-router.zunda.co.jp/en/faq#device-return-on-cancel
If you contract directly with ZUNDA, the product is provided as a subscription service, so you will need to return the equipment upon cancellation. If you contracted through a retailer, please contact that retailer.

### Could the management path ever be exposed to the internet?
https://connect-router.zunda.co.jp/en/faq#management-path-isolation
No, it cannot. Management traffic from ZUNDA CONNECT, the cloud-based management platform, to ZUNDA CONNECT ROUTER uses a dedicated, closed mobile connection that is separate from the internet. It is designed so that no management port is ever exposed on the WAN side.

### Do I need to open a port for remote management?
https://connect-router.zunda.co.jp/en/faq#no-port-forwarding
No, you do not. There is no need to open a management port on the WAN side to manage the router. Rather than creating a login entry point from the internet, management is carried out through a closed management path.

### What size of environment is ZCR designed for?
https://connect-router.zunda.co.jp/en/faq#target-scale
Mainly office environments with a few dozen to a few hundred people. It is optimised for site-based use rather than individual use.

### Are there any initial costs?
https://connect-router.zunda.co.jp/en/faq#initial-cost
There are no initial costs. The product is provided as a subscription service.

### Please tell me about the pricing structure.
https://connect-router.zunda.co.jp/en/faq#pricing-overview
ZUNDA CONNECT ROUTER is provided as a monthly subscription service (¥15,000/month) that includes the hardware unit and the cloud management feature.

### What is included in the monthly fee?
https://connect-router.zunda.co.jp/en/faq#monthly-fee-inclusions
The monthly fee includes the ZUNDA CONNECT ROUTER unit itself, the cloud management feature, the dedicated management mobile connection, software updates, and maintenance support. A 19-inch rack-mount bracket is also included.

### What happens to pricing if I deploy multiple units?
https://connect-router.zunda.co.jp/en/faq#multi-unit-pricing
We expect contracts to be tailored to the number of units and scale of use. If you are considering use across multiple sites or a phased rollout, please contact us individually to discuss. If you would like to handle the product on an ongoing basis as a sales partner, separate terms can also be discussed.

### What support do you provide in the event of a fault?
https://connect-router.zunda.co.jp/en/faq#failure-handling
In the event of a fault, we will replace the unit. The cost of replacement is included in the monthly fee, so no additional charge applies.
Because configuration data is managed in the cloud, simply reconnecting the cables to the replacement unit restores the settings automatically, with no need to reconfigure anything.

### Do you support site-to-site VPN?
https://connect-router.zunda.co.jp/en/faq#site-to-site-vpn
Yes. We support site-to-site VPN, which securely connects sites such as head offices, branches, shops, and factories to one another.
WireGuard and IPSec/IKEv2 are both supported, and the measured throughput figures are as follows.
- WireGuard: approx. 3.76Gbit/s
- IPSec: approx. 2.31Gbit/s

We recommend using WireGuard, as it is faster, has lower overhead, and offers simpler key management. Our managed mesh VPN automatically connects multiple sites in a full mesh, and adding new sites can also be managed centrally from the cloud.

## Configuration (admin console)

Configuration is done primarily in the admin console (GUI). As you fill in the fields in each GUI section, the input is automatically generated as JSON configuration. If you prefer, you can also edit the generated JSON directly as text. You can move back and forth between GUI and text at any time; before applying, the server validates the structure and consistency and points out any problematic locations.

Configuration consists of the following sections: Network (WAN / LAN / ports / static routes / VXLAN / VPN), Firewall, Services (DNS / DDNS / SQM), and System (hostname / timezone / maintenance windows). The items and values you can set in each section are as follows.

### Network › WAN (internet connection)
Each WAN has ipv4 and ipv6 connection methods (arrays).
- IPv4 mode: dhcp / static (address and gateway required) / pppoe (username, password) / ds-lite (aftrServer) / map-e (provider: v6 Plus, OCN Virtual Connect, Xpass, etc.) / ipip6 (remoteEndpoint, localAddress) / disabled
  - dhcp, static, and disabled are specified alone. pppoe, ds-lite, map-e, and ipip6 can be combined (tunnel types require a valid IPv6)
- IPv6 mode: dhcpv6 / slaac / static / pppoe / pppoe-shared / disabled
- Optional: vlan.id (1-4094), mtu (576-9999), DHCPv6 prefix delegation

### Network › LAN (internal network)
- Multiple LANs allowed. Exactly one must be default: true
- ipv4: mode (static / disabled), address (CIDR, /1 to /31)
- ipv6: ra and dhcpv6 (server / relay / disabled), ndp (relay / disabled), multiple static addresses allowed
- dhcp: enabled, rangeStart / rangeEnd, leaseTime ("12h", etc.), DNS distribution, reservations (static MAC→IP assignment)

### Network › Ports (physical port assignment)
- access mode: assign to network (defaults to the default LAN if omitted)
- trunk mode: networks (aggregate multiple via VLAN tags), nativeNetwork (native VLAN)

### Network › Static routes
- destination (CIDR), gateway; for LAN/VPN/VXLAN destinations use interface, for WAN destinations use wanConnection, with an optional metric

### Network › VXLAN (L2 extension tunnel)
- vni, remote (remote VTEP), optionally port (default 4789), bridgeTo (LAN), sourceAddress

### Network › VPN (site-to-site)
- WireGuard (manual): privateKey, listenPort, addresses, peers (publicKey, allowedIps, endpoint, persistentKeepalive, presharedKey)
- WireGuard (managed mesh): specifying vpnGroupName automatically full-meshes the multiple sites in the group
- IPSec / IKEv2 (site-to-site): gateway, preSharedKey, ikeProposal / espProposal (encryption: aes128 / aes192 / aes256 / aes128gcm / aes256gcm, hash: sha1 / sha256 / sha384 / sha512, dhGroup: modp1024 to modp4096), localSubnets / remoteSubnets, dpdInterval, ikeLifetime / childLifetime

### Firewall
- defaults: input / output / forward (accept / reject / drop)
- zones: members (WAN/LAN/VPN/VXLAN), input / output / forward, nat (masquerade)
- forwardings: allow inter-zone forwarding from → to
- rules: name, source / destination (zone name / "*" = all destinations / null = the router itself), protocol (tcp / udp / tcp+udp / icmp / esp / igmp / all), srcPort / dstPort ("80,443" or "8000-8100"), srcAddress / dstAddress, family (ipv4 / ipv6), icmpType, limit ("1000/sec"), action (accept / reject / drop)

### Services
- dns: upstreamServers, cacheSize, localDomain, rebindProtection, staticRecords (hostname → address)
- ddns: provider (transix / v6plus / v6connect / xpass / other), sourceConnection (the WAN to use)
- sqm: interface (WAN), download / upload (kbps), queueDiscipline (cake / fq_codel)

### System
- hostname (RFC 1035), timezone (IANA, e.g. Asia/Tokyo)
- maintenanceWindows (at least one required): dayOfWeek (0=Sunday to 6=Saturday), startTime (HH:mm), durationMinutes (60-1440, multiples of 60), timezone

### Key value ranges
Port 1-65535 / VLAN ID 1-4094 / VXLAN VNI 1-16777215 / MTU 576-9999 / IPv4 prefix /1 to /32 / IPv6 prefix /1 to /128 / LAN prefix /1 to /31

### Validation
Before applying, the following are validated: referential integrity (port→network, zone members, route destinations, etc.), uniqueness of the default LAN, no subnet overlap between WAN/LAN, validity of the DHCP range, and uniqueness of VPN names and IPSec ifId.

## How to proceed with configuration
1. Configure the items in each section in the admin console (GUI) (the main method).
2. The input is automatically generated as JSON configuration.
3. If needed, you can edit that JSON directly as text (also convenient for Git management and review).

Before applying, changes are validated server-side and any problematic locations are indicated.
