274478 2004-09-22 00:55:00 My rellies in the UK have discovered Messenger, So I have had to set up, etc. However, I'm having a problem with Audio connection (Video is OK) It appears to be a firewall problem. I am running Zone Alarm Pro, and the only way I have been able to get SOME Audio is to disable ZAP. I have checked Search on this site, and E-mailed MSN and ZA for help. The best reply I have had is:
"MSN dynamically assigns ports for audio using UPnP. By opening UPnP port 5000, you can use audio."
This appears a better option than closing down ZAP, but it's a bit technical for me. How do I do it? Regards

274479 2004-09-22 01:40:00 Sorry, should have added: WinXP Home, Xtra 1Gb Broadband, Dell Dimension 4600. kbcad (1025)
274480 2004-09-22 01:47:00 Is XP's firewall on? Turn it off if it is. If you have ZA installed. See if it makes any diiff Spacemannz (808)
274481 2004-09-22 02:31:00 Thanks for you reply, Spacemannz - can't find any sign of a firewall in my version of XP, despite the Help info. telling how to diasable same, the instructions did not tally with what came up on my screen. KB kbcad (1025)
274482 2004-09-22 04:25:00 its under the dialup/properties/advanced 1st option the firewall. If this is ticked the firewall is on. Spacemannz (808)
274483 2004-09-22 07:59:00 Thanks, Spacemannz - checked the firewall and it was not on. KB kbcad (1025)
274484 2004-09-22 08:56:00 I would say you'll have to find out what port MSN uses for audio. And add it to ZA. If it has the option. Spacemannz (808)
274485 2004-09-22 09:53:00 Network Address Translation, NAT, with an ADSL router can cause audio/video problems with MSN Messenger, in fact Ive never had satisfactory results with MSN, but with Yahoo Messenger, no problems at all.

The Help files in ZA should tell you how to open port 5000, I'd suggest opening it for UDP packets in both directions, but I dont use ZA so can't be precise.

274486 2004-09-22 10:51:00 Just been refreshing my memory by a bit of Google.

Audio uses port 6901, TCP out, UDP in and out.
You should also enable unpnp in your router.

(That won't necessarily guarantee audio working though :) )

274487 2004-09-22 23:48:00 Thanks to Terry and Spacemannz - your advice is a bit too technical for my ability. However, the idea of changing to Yahoo Messenger appeals if it is problem free. Would you recommend it, Terry? kbcad (1025)
