Tech note port discrepency

Question

I'm trying to follow all your recommendations for getting iChat AV to play well with others, but not having any luck. I haven't given up but want to point out a discrepency between TROUBLE SHOOTING REVISITED and Apple Tech Note 93208 Using iChat AV with a firewall or NAT router.
The discreption of whether certain ports to be opened are TCP or UDP is where the difference lies. For example, the tech note says:
1. All iChat AV traffic is UDP except for ports 5190 and 5298, which need to be open for both TCP and UDP; and 5220, 5222, and 16384-16403, which need to be open for TCP only.
2. Ports 5297, 5298, and 5353 are used only for local traffic. Opening these ports may be necessary for firewall software that runs on a computer, rather than on a router. These ports do not need to be open at your uplink to the Internet.
Note that this is also the tech note that comes up in iChatAV HELP.
Note too that port 5298 is listed twice in TSRevisited under UDP. Not sure if one of those was supposed to be another number or not.
Thanks

Hi Bruce,
This post has dropped n to the Second page at present http://discussions.info.apple.com/webx?128@@.68bcb01b
Note 1. becomes clear if you read it like it read previously but add the Jabber port info.
1. All iChat AV traffic is UDP except for ports 5190 and 5298, which need to be open for both TCP and UDP; and 5220, 5222, which need to be open for TCP only.
Regarding note 2. I had note spent that much time re-reading that one and it has not in fact changed.
I would add that I recommned that these ports are opened in a router that sits behind the modem if it is the device that routes. I would further add that if the modem is the only device that routes these ports my need to routed to other computers on the local net rather that to open them to the internet.
