Hello all. I have router bcbehind connected to my cable modem. I can ping out and resolve domain names. bcnetworked is connect to bcbehind via serial connect. ser0 connects to ser0. I am able to ping from bcnetworked up to the cable modem. I can't ping out. I believe it is something with bcbehind's config any help would be appreciated.

Hi,
Ok, thats the catch, you'll need to NAT bcnetworked IPs on the cable modem.
HTH, please rate if it does help,

Can you post bcnetworked configuration.

Hi,
If i understand you right then BCNetworked can ping both bcbehind and the cable modem, but it can't get outside, you have to consolidate one thing, routing is a 2 way process, thus for a ping to succeed the packet must know how to go from BCNetworked to outside and then back from outside to BCNetworked, does the outside (your provider) route the IPs of BCNetworked back, or are you doing NAT on the cable modem and the IPs of BCNetworked is not included.
HTH, please rate if it does help,

Nat is being utilized. The ISP is not involved.

That was very helpful. I was able to determine at the issue is my cable modem will not allow to allow any other networks other then the 192.168. network. Because of this I had to subnet the 192.168.0.0 to accommodate my needs since the cable modem would not allow me to enter the 10.0.0.0 network. Now both of my routers can ping all the way through. I appreciate the help.
