I dunno. Ghostwall doesn't seem to monitor my outgoing packets quite properly. However, other software like Traffic XP Shaper can monitor them without any problem. I don't want to use that software because it messes up with XP sometimes.

My laptop has to be DMZ'd, otherwise PS3 connecting to it won't be able to use the Internet via my router at all. I've tired port forwarding but for some reason that didn't work.

Software like PeerGuardian 2 worked fine, but it doesn't have the 'Block or allow incoming/outgoing packets' function.
