I am trying to get traffic from fa0/1 to fa0/0 for my wan. I have a comcast modem attached to fa0/0 and then I have a cisco 3750 attached to fa0/1 with a couple PC's attached to it. Currently the switch can ping 10.10.10.1 (1841 router) and 10.0.0.135(comcast modem fa0/0 interface) however it can't ping 10.0.0.1(comcast modem)
