IR route question

Hi all, working on some more fun stuff at work and found a weird one.

​

IP route issue with a quad zero. I have to have a router with an outside interface set to DHCP, the ip route is setup to use the interface instead of gateway IP however no traffic will flow. I assume it is because its not a dedicated P2P link.

​

Is there a trick I have not yet learned for making this work?

​

ip route 0.0.0.0 0.0.0.0 g0/0/0

int g0/0/0

ip add dhcp

​

that is really the extent of it.
