I have a unix server on an internal network, behind a ComCast SMC8013WG Cable Modem / Router. All of my PC's and MAC's on my internal network can see the sever and access it. They can all see and access the internet as well. All except for my Unix Server. I need to get remote access to this unix box ... I have set up port forwarding in the ComCast Cable Modem ... but I cannot PING anything outside of my internal network from the unix box. I am sure it's something simply-stupid that I forgot to do, but for the life of me I cannot get this straight. Any suggestions?
