I searched but couldn't find anything on this.

In Panther, I knew what ports to open in my firewall in order to use iChat AV (5060, 5190, 5297, 5298). But with Tiger, there is now a choice between TCP and UDP. Which do I choose? I'll be chatting with both Mac and PC users.

Thanks in advance...

Wow. No one knows?
