Watchguard Firebox III 700 DHCP Rule

[callum]

Heya Everyone,

This one is for the Watchguard gurus out there..

I've not long finished installing and setting up a Firebox III 700 in Drop-in Mode. Installation as follows (Cannot be botherd to snap up a Visio diagram)

External NIC: Modem
Trusted NIC: LAN
Optional NIC: Server / WiFi AP

Everything is working fine, All the required services are configured (HTTP, IMAP etc). However I have the server manage DHCP, But after adding the service and configuring it, DHCP still doesn't work.

I've tried the following on both Incoming and Outgoing:

From: Trusted
To: Optional

From: Trusted
To: 172.16.11.250 > 172.16.11.254 (NAT)

As well as various others Including From: as being Any. Yet DHCP still fails to dish out IP Information. However DHCP will however function on the External NIC, As Connecting a WiFi device will receive DHCP just fine. So It's the communication between Trusted and Optional.

It's a little mind boggling since everything else works fine. DHCP in the Router as well as the Firebox has been disabled to rule out possible conflict.

Any help would be appreciated

Regards
Callum

Which interface (ip) is the dhcp server listening on as it could be that it's just bound to the interface that it works on. DHCP requests are a broadcast and will not pass through a router (unless you have dhcp relay / ip helpers configured)
