a shared ip? do you mean a dynamic internet ip? it can be done, if you feel like forwarding your ports and changing your severs ip every few whatevers.

You cannot share an ip address on the internet lol. Go to dyndns.org. Setup the account and download the software. Everytime your DYNAMIC ip address changes, your computer will update it with dyndns automatically. They have a domain especially for game servers so all people have to dype is yoursubdomain.gameservers.com
