Here is my situation:
Cisco 1721 connected to linksys cable modem on WIC0 ethernet connection gaining IP via DHCP. Fastethernet0 connected to local LAN.
Problem:
From my laptop connected to the LAN if I ping a website such as google.com, it resolves it to an IP address but times out with the packets.
I am trying to set up NAT on the cisco but can't figure what I am missing.Below is a copy of the running config.
Any help would be greatly appreciated, I have been working on this for 2 days straight now.

I would double check that statement. I had the same issue, and that was the cause. I am assuming you have someone like comacst for cable. Well you cable modem is getting the 10.x.x.x address and your router is getting the real address 68.x.x.x. Best way to determine this is to either remove the route statement or at bootup have debug dhcp detailed on to find the real gateway.

The problem was the IP address I was recieving from Cableone. They make you register you MAC address before handing out a routeable IP address. I had to change the MAC address of my outside interface to match that of a registered NIC. Everything is working now.
Thanks

I had a similar problem... and go to the linksys config and on the dynamic routing tab enable RIP2. That seemed to make a diff for me...
