Windows Live Messenger Ports

Hello all,
Hope it's the right forum (move if not ).
I'm using Jetico V1 and stumbled upon an article in Microsoft support site that lists all the ports being used by WLM under Vista/XP.
I said to myself this could be a great reference for setting a correct table for WLM in Jetico, however, I could not completely understand the article.
It only states TCP/UDP without stating the "direction".
As far as i know, in Jetico, TCP is "inbound/outbound connection" and UDP is "send/receive datagrams" (correct me if i'm wrong).
Anyway, can someone please take a look at this and tell me from their own experience, what does MS means by the listed ports? (I'm referring to the bottom table, i have an XP-based system).
I guess i should not interpret every entry as a rule in both directions (both in and out).
Thanks in advance, Adam.

As you can see, Windows Live Messenger uses prts ranging from 1-65000 these change everyday or so, so setting a firewall to accept WLM with these ports isnt alwaysa good policy. The best policy for Windows Live Mesenger is to Allow All Activities, this way It'll keep running smoothly. I dont know about Jetico,cause I have never looked at it, but from a personal experience Outpost would refuse Auto Connection to WML on bootup, as it blocked port 1900. Why they did this I have no Idea
