I’m running Messenger 6.1 .0207 on an XP Pro platform running Zone Alarm Ver4.5.538 and I can’t get the audio to work through the firewall. I have tried the reg hack for changing the port to 80 but this doesn’t work, I have trolled through loads of info on the net but can’t seem to find a fix.
An idea that I thought of would be to make an exception rule in the firewall for the Messenger Server Ip Address and allow the UDP ports open for that address ? Does anyone have those details ?
Any other idea’s are more than welcome.
Thanks in advance

Microsoft actually is kind enough to tell you which ports Messenger uses for what. There is this article http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/winxppro/deploy/worki01.asp where you can find usefull information regarding this issue.Quote:quote: The actual Real-time Transport Protocol (RTP) streams are sent using dynamically allocated UDP ports in the range of 5004 – 65535. Without a way to open these UDP ports on any firewall in the path dynamically, the streams will fail to reach their destination.
This site is really interesting too http://www.hypothetic.org/docs/msn/client/invitation_types.php
And you can definitelly find priceless information regarding MSN port usage in BBB Search Tool:

Soooo annoying that Messenger has to be such a port hog ! I don’t really fancy leaving 60,000 ports open – guess i’ll have to adjust ZA everytime I use it or prey that they will upgrade to a UPnP firewall. I will post a request and see what they say.
