Manual DHCP Known Devices

DHCP & Known Devices

Two related pages: Connection → DHCP for configuration, and Status → Connected Hosts for a live, read-only view of what's actually on your network right now.

Connection → DHCP

DHCP server (IPv4)

• LAN DHCP Server Enabled — master toggle.
• DHCP range — Start / End of the address pool handed out automatically.
• Show advanced (alternative gateway) reveals an option to point DHCP clients at a different default gateway than the router itself. A clear warning is shown when you enable it: devices using the alternative gateway send their internet traffic through that other device instead of this router — which means bandwidth monitoring, quotas, access restrictions, and QoS on this router will not apply to them. Useful for handing a subset of devices off to a separate firewall/VPN box, but worth understanding before you flip it on. See Other New Features for more on this feature.
• Lease Time — now settable directly in minutes (previously hour-only).

DHCPv6 / IPv6

DHCPv6 and Router Advertisements each have their own Enabled / Relayed / Disabled state, plus a SLAAC toggle and a read-only display of your current IPv6 address prefixes.

Devices (static leases / Known Devices)

• Enforce DHCP assignments — when checked, only devices you've explicitly configured below get a lease; everything else is refused (a MAC allow-list, effectively).
• Add Device — pick a currently-connected host from the dropdown to pre-fill the form, or add one manually. Each device entry has:
  • Hostname (optional)
  • MAC (required)
  • Fixed IP (optional) — give this device the same address every time.
  • Group (optional) — a free-text label like family, iot, work, kids. This is the Device Groups feature: name a group here once, then target that same group directly from Restrictions or Quotas instead of listing individual devices in both places. An autocomplete dropdown suggests groups you've already used.
  • Show advanced (IPv6 reservation) reveals an optional IPv6 Suffix and DUID for IPv6-specific reservations.

Validation catches duplicate hostnames/MACs/IPs, a static IP or DHCP range falling outside your LAN subnet, and a DHCP range that would include the router's own LAN IP.

Status → Connected Hosts

A live, read-only dashboard — not something you configure, but the place to check what's actually connected:

• Refresh Rate — how often the page reloads itself (2/10/30/60 seconds, or never).
• Current DHCP Leases — active leases right now.
• Connected Wireless Hosts / Client Wireless Connections — WiFi-specific detail including bitrate, signal, and band.
• Hosts With Active Connections — active/recent TCP and UDP connection counts per host.

This page is also where the "select from currently connected hosts" dropdown on the DHCP page pulls its list from, so a device needs to have shown up here at least once before you can quick-add it as a static lease from a dropdown (you can still always add one by hand with just its MAC).
