DHCP not working on second interface

[KOM]

Do you have DHCP specifically enabled for that interface?  Post your DHCP settings for the interface in question, as well as the firewall rules for it.

You could always sniff the traffic and see if the DHCP handshaking is happening, and which side isn't responding.

[sam_maher]

Thanks for the speedy reply, Yes DHCP is enabled for that interface.

Please see attached for the settings

Edit: Here is the output for wireshark. Looks like pfsense isnt responding

Looks good so far.  What do you get if you capture on pfSense OPT1?  Does it see the request?

[sam_maher]

This is what i got from PFSense

That looks like the interface on the client.

On your router do a Diagnostics > Packet Capture on OPT2 and try to get a DHCP lease again.

[sam_maher]

That was the packet capture from PFSense, Ive imported it into wireshark

Stop and restart the DHCP service or reboot I guess.

[sam_maher]

Have tried that, No luck :(

Anything in the advanced config of the DHCP server?

[KOM]

… or the general System log?

[sam_maher]

No there is nothing in the advanced config and here is what i have found in the log:

Well seems you got something listening on that interface and you can not bind to it..

[sam_maher]

Thats what i thought, Im trying to bind to "igb0".  "igb1" is the current LAN which works fine.

I have tried restarting DHCP and changing the IP range with no luck.

DHCP Relay somehow enabled on that interface?

See if you somehow you got past the GUI logic.  Disable all your DHCP servers and see if DHCP Relay is enabled?  Just a guess.

[sam_maher]

Just checked and the dhcp relay was not enabled.

Check the output of 'sockstat -4', it'll show you which process is bound to that port already.
