I have a private ip say, xxx.xx.xxx.xx:xxxx
And I have a different public ip say: yyy.yy.yyy.yy
How do I allow my private IP(i.e. my machine) to be reachable to the public internet(for a condition zero server here). Also, my IP is assigned to me by my ISP, it changes every few days(but that don't matter because I only have the server running when my PC is on and I can start it each time). But I don't have a Modem/router in my home, except for the LAN card of course. My net just plugs into my LAN port, I dial an assigned username/password and am connected to the WWW.
Any help would be appreciated.
