WAN gateway doesn't come up after a power loss to the cable modem - I need to manually release and then renew DHCP lease
-
Hello!
First of all, sorry if this is the wrong sub-forum. So far I think I have drilled down my troubleshooting to say that my issue is somehow DHCP client related.
I am running pfsense 2.7.2-RELEASE (amd64). The WAN port (interface igc0) is connected to a Technicolor cable modem (in bridge mode). When I cut the power to the cable modem, and then restore power, the WAN gateway doesn't come back up:
In my logs I see:
When I manually release and then renew the WAN interface's DHCP lease, the gateway comes up.
I am at loss on where to look for configuration errors, or tweaks that I would need to make to my configuration.
All help is very welcome!

@alainf That's not the correct part of the log you are showing. If your Modem looses power pfSense should see a link-down event on it's WAN, and a proper link down should have pfSense attempt to renew its DHCP - and if not try to aqquire a new DHCP lease.
But if there is no link-down event involved - then you are in similar trouble to many others because pfSense offers no automation to actually release/renew WAN DHCP addresses.
