DHCP not working on second interface

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.

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

Stop and restart the DHCP service or reboot I guess.

sam_maher · Oct 7, 2015, 3:57 PM

Have tried that, No luck :(

Anything in the advanced config of the DHCP server?

KOM · Oct 7, 2015, 4:28 PM

… or the general System log?

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..

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 · Oct 13, 2015, 7:03 PM

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.
