891-W Comcast DHCP on WAN interface config

[Erik Kaiser]

Hi,

I need some help configuring DHCP on my WAN interface for my ISP Comcast.

Here is my WAN port configuration so far. I am not sure what I am missing but I am not recieving any IP information.

interface GigabitEthernet0

description ISP INTERFACE

ip address dhcp hostname R1

ip nat outside

ip virtual-reassembly

duplex auto

speed auto

Hi

Could you do the below:

int g0

no ip address dhcp hostname R1

ip address dhcp

Make sure you have a default route:

ip route 0.0.0.0 0.0.0.0 dhcp

Thank you already made the change. I had it working previously but erased my config and forgot how to reconfigure it.
