I have a c881 with an interface configured to grab DHCP from a cable modem. However I keep getting
"Timed out Selecting state%Unknown DHCP problem.. No allocation possible"
I've rebooted the cable modem, I've done all I can think of.
description Backup to cable modem
ip vrf forwarding isp2
ip address dhcp
ip nat outside
ip inspect XXXFW_BKP out
This is the interfaces configuration and this works on all my other routers.
Any help would be great.
Also there are no access-lists that would stop this.
