NAT and PAT
Here's my situation. I have a public ip address which is beging "natted" to my web server inside the LAN. There's another PC inside the LAN which is being employed to broacast radio on port 8090. Is it possible to port forward from that PC to mine so that I can make it publicly available on the Internet? If so, how can this be achieved and are there any GUI tools (for GNOME and Ubuntu, for instance) that can make the job a little easier?
