pfSense cannot get WAN IP address
-
First I've ready many posts about this same issue, but have not found a resolution.
Last night about 2:30AM my router lost connection to the internet. My investigation shows that the pfSense router will not get an IP address from Comcast DHCP.
I can connect a laptop to the modem, that is running in bridge mode, and get an IP address.
I am running version 2.3.5 of pfSense.
What I see on the status dashboard for my WAN interface is a green up arrow and n/a or sometimes 0.0.0.0. If I SSH into the router the initial status page shows blank for WAN, although once I saw it with a valid IP very briefly.
In the logs I see an entry like this:
/rc.Linkup: The command '/sbin/route change - inet default '24.16.40.1'' returned exit code 1, the output was 'route: writing to routing socket: no such process route: writing to routing socket: Network is unreachable change net default: gateway 24.16.40.1 fib 0: Network is unreachable'
Before this happened my IP address was 24.16.42.2
I'm at a loss for how to resolve this so any help would be awesome.

I would:
- Disconnect the pfSense WAN from the modem
- Power cycle the modem
- Let it sync back up
- Reconnect to the WAN port.

Thanks. I've done that many times, but no joy.

DHCP from Comcast

@weswitt What is the WAN provisioning? DHCP? Static? PPPoE?
Ah I see DHCP. What is in the DHCP logs?

I was able to get things working again by reinstalling pfSense 2.4.3. Sad that I had to nuke my router to get it working again

Doubtful that was actually necessary. But if that's what you have done, that's where you are now.
