Proxy Server?

[Joe]

Hey, I've got two computers networked on my desk, a MacOS X box and a Windows XP box. I never connect the Mac OS X box to the internet, but I'd like to do some software updates and stuff. I've run software on my computer that ran a proxy server so that other computers on the network could ask the proxy server to go grab something, and it'd be like its on the internet, but I can't find it. Any suggestions?

PS: Yes, yes, google. I'm on my way, but if anyone knows a good one, I'll just use that.

I <3 My Mac.

(Yeah, that means I got it working.)

[edit]Haha, and it shows my Mac's Intranet IP on here instead of my Dell's Intenet IP.[/edit]
