Firewalls
 

what's a good firewall that will allow games through, ie one that allows you to change ports easily. doesn't have to be really simple like zone alarm or netnanny, I can probably figure out most anything.

I'd have no bloody idea o.o

Zone Alarm works fine for me.
Sygate is supposed to be really good too.

McAffee and Norton are both pretty dicey.
And I don't know anything about BlackICE Defender except the name.

Personnaly, I use Stopzilla (I'm not kidding).
It works really well!

where's the web site for stopzilla? I might want to use that one.

www.stopzilla.com
Although you can only get the trial, but there is a way. . . to illegally. . .get a . . .key!
I can't tell you more, the cops would bust my place in 10 secs :D

Stopzilla's main point seems to be that it blocks popups. they are annoying, but sometimes I want them.
