Networks Bridging/Sharing a network connection

I'm sorry if this has been asked before, but possibly it's faster for me to just ask then to dig through all the threads in this topics...

I have 2 computers now, and only one computer with a connection outwards...
Windows XP pc has Wifi towards the outer world, and my other computer, running Windows Vista (beta *** ) is connected to my pc by LAN cable (crosslinked, ofcourse (a switch between it actually))

Now what I want to do is use my XP computer to bridge that Internet connection for my Vista computer. I found the 'Bridge these devices' function in my control-panel, but can't find out how to configure it so that both my XP compu and Vista computer have an internet connection... I actually haven't had any Internet connection with my Vista pc yet at all...

Any networking guru/administrator/freak/whatever you want to call yourself who can help me?

 

Right click on the connection you want to share, and click on "sharing" (SHOCK HORROR) follow the wizard.

 

yeah, that's what I already tried... even tried using a proxy, but my other pc didn't seem to like the idea of a proxy, it somehow didn't resolve IP's correctly, as it passed everything to the first IP it got, being google.com's IP

but anyways, don't really need to know anymore, because I'm getting wired very soon, most likely tomorrow
