Existing dhcpd configuration detected

This router has a /etc/dhcpd.conf that OgmaProtect does not manage. Applying from this page replaces it with the settings below. The current file is preserved to dhcpd.conf.preadopt before the first overwrite, and shown read-only here — it is never imported automatically.

{{LIVE_PREVIEW}}

Preview truncated — the full file is preserved on adoption.

Configured {{ENABLED_LABEL}} Server {{RUNNING_LABEL}}

The server's service state does not match the configuration — applying re-synchronizes it.

The live /etc/dhcpd.conf differs from the saved configuration (hand-edited, or never applied) — applying overwrites it with the settings below.

Rendered dhcpd.conf preview

Read-only /etc/dhcpd.conf rendered from the saved configuration (re-rendered after each save; unsaved edits are not reflected).

{{RENDERED_PREVIEW}}

Preview truncated for display — validation and drift always use the full render.

{{#ADOPTION}} {{#WRITE}} Take ownership of the existing dhcpd configuration (preserved to dhcpd.conf.preadopt, then replaced) {{/WRITE}} {{/ADOPTION}} {{#WAN_CONFIRM}} Serve DHCP on {{WAN_IF}} even though it carries the default route — I understand this runs a DHCP server toward the upstream/WAN side, which is almost always wrong {{/WAN_CONFIRM}} {{#WRITE}} {{/WRITE}}

Firewall

Ensure your firewall passes UDP ports 67 and 68 on {{HINT_SUBNETS}} so clients can reach this server. This page never changes firewall rules — manage them on the Firewall page.
