sharing internet connection between pc and mac

[kikkand]

Hello

I have a PC with an internal modem that connects to the internet via 3g+. it's got wi-fi as my macbook.

i want to share the internet connection of the pc via wifi (using what is called an "ad hoc" connection ( a pc to pc network)) so that the mac can connect to the pc (via wifi) and use its internet connection.

i've already tried a bunch of things but they don't work, can someone help me or tell me where i can find a GOOD guide to do this? (i've already looked around but i haven't found anything that works)

thanks

well the problem is a bit different because i'm using windows xp and i don't have a router....

i know...with a router it would be much easier. but i don't have it....
