Recently replaced a 1710 with a 1941 Cisco router. It is the same config and instead of going to the internet form the cable mode (Cable Modem GW 12.14.4.13) it goes over the T1 and gets on the internet from the cable modem there.

What am i missing?

This same config works on Cisco 1710 just fine.

Your default ip route needs to be changed to the next hop router IP address which is connected to serial0/0/0:0

The following is a from another 1710 that has a local cable modem and a bonded T1 back to the data center. This building uses the local cable modem for internet traffic with the following config.

I just wnat to have all of the workstations to use the lcoal cable modem for internent traffic and not go over the PTP T1 and get it.

Can you post a diagram with ip address on each interface?

no ip route 0.0.0.0 0.0.0.0 12.14.4.13

ip route 0.0.0.0 0.0.0.0 192.168.6.2

Does the switch have default gateway set up to 192.168.6.8?

Also the firewall should have 12.14.4.x IP address, correct?

Thanks.

If that doesn't work (I was under assumption that you have a default route on the switch pointing to 192.168.6.8) try below:

no ip route 0.0.0.0 0.0.0.0 192.168.6.2

ip route 0.0.0.0 0.0.0.0 192.168.6.8

Ok. I got it working by adding the Firewall instead. (192.168.6.8)

The switch's GW is the the router (192.168.6.1)

Thanks.
