ok, i am running 2 win xp pro comps in my house.. networked with a crossover cable, and 2 nics in server, 1 in host.. so now.. the host computer. "my computer" has a static ip address and i want a real one so i can use vnc.. with vnc "virtual network computing" u need a real ip address to get your remote computer on the net.. so now.. is there ANYWAY for my computer to get a real ip address without spending any money or moving anything around????? would port redirection work, and if so, how would i do it, or NAT???? would that work?? im thinking redirect the vnc connection to the server, up to my computer.. any suggestions.. i cant get anything to work?
