Network gameing over the internet

i like to play games like star craft and red alert2 with someone else using the internet

and i want to let the games think that i am playing with an LAN

i heard that i should forward some router ports directly to my computer.
and then the other person should do the same (if behind a router)

but i’m really a newbie with all the technical stuff so i was wondering wether or not this will work?

and what’a ports should i forward?

i’m using winxp
thanks !
