So I used to forward ports all the time, normally single computers. Now at home I have 4 computers running through a router on my network. I am not sure if I can forward ports on a network. I need to forward port 7777 for Unreal Tournament 3, to get a certain problem fixed with the game. That is besides the point. All the information on how to do this 100% is right here, http://www.portforward.com/english/routers/port_forwarding/Belkin/F5D9230-4/Unreal_Tournament_3.htm. Now in that tutorial it says you need to have a Static IP address, which I knew. How to do that is right here. http://www.portforward.com/networking/static-vista.htm My question, if I follow that tutorial on getting a Static IP address will it effect my other computers and not allow them to use the internet? I know I tried this in the past and I think they still had internet but it was not stable, if that is what I did, can't remember. Anyways, is it safe to do this?
