Audio Fails - Windows Messenger

[Martin]

OK, I know this subject has been thrashed out but if someone could possibly
give some advice it would be very much appreciated.

Setup:
*Windows XP Pro, SP2 (Windows Messenger 4.7)
*ADSL connection via NetComm NB1300 ADSL Modem Router, connected via LAN
(router is connected to a LAN switch which networks the ADSL to 3
computers).
*ZoneAlarm Pro (Windows Firewall is disabled).

Messenger (and Yahoo Messenger) connects and I can type messages, but when
either party clicks "Start Talking" once the invitation is accepted it fails
to connect - after about a minute it tells you there was a problem
connecting to the other computer. ZA has been set to allow Messenger...

I presume this problem has something to do with the router rather than
zonealarm. I use another VoIP program (echolink) which works fine but I had
to set port forwarding on the modem and also in zonealarm - if this needs to
be done for messenger does anyone know what ports need to be set? Not
interested in video, just audio..

Thanks for your patience and assistance.

Do you have UPnP enabled in your router?

Do you have UPnP enabled in your router?

I'd gladly answer this if I could find any reference to it in the
configuration or manual!! I would've presumed that as it is fairly new it
would've had UPnP but I can't find it mentioned in the manual, and certainly
can't find it in the configuration settings.

Anyone out there with the NB1300 know any more????

Do you have UPnP enabled in your router?

Further to this question, I contacted NetComm technical support and their
advice was that port forwarding will have to be setup to enable the router
to work with messenger.

I've setup the port forwarding before for another program (echolink), so
that isn't a problem, if someone can tell me what ports are needed by
Windows Messenger for audio to work? I don't need video, just audio.

Yes, I have tried to search this subject and found a heap of information
that contradicts other information, so if you (or anyone else) would know
what ports are needed for audio I can try that to see if it works.

TIA
