Hello,

I need some advice.

I am attempting to get a Cisco SB101 Router to work behind a Comcast Business Class Modem w/ built-in SMC Router. We are assigned 5 static IP's from Comcast--the Modem/Router uses the .50 address, with the other 4 just below this. According to Comcast, all one must do is to assign the Cisco Router a static IP of, for example, .49 w/ subnet mask, then somehow specify it to use the SMC Modem/Router as a Gateway (using the .50 address as the gateway address). As of right now, there is a Linksys Router in place that works jsut fine--can access from outside world using the .49 address.

The Cisco does not allow me any I-Net access on the inside, and needless to say, no outside-> in access either.

If anyone has any advice, please help! Thanks.
