VOICE OVER MSN

[AGaddoni]

Dear Sirs,

Few days ago, I posted a problem regarding MSN connection through proxy server using your software WINGATE (unfortunately I did not find it any more on the forum).
We have a local network with a DOMAIN SERVER with DHCP SERVICE; outside the domain a proxy server, for internet connection, with WINGATE updated from version 5.xx to version 6.
Our WINGATE configuration:
1) DHCP service: DISABLED (dynamic IP obtained from DOMAIN SERVER).
2) User and group management: MANUALLY CREATED - NO USER DATABASE FROM OS.
3) NAT: ENABLED (however in the SYSTEM MESSAGE LOG we find “authentication failed - user guest on 192.168.x.x requested NAT: UDP...”).

Well, my clients are able to send and receive instantaneous messages and also webcam-video connection seems to run (sometimes fall down the connection); my problem now is that NO MSN AUDIO is transmitted or received from the clients.


I checked the post you suggested me but no solution appears to solve my problem.
Can you help me ?

Best Regards
Alessandro

Dear Alessandro,

The problem you have with sound on MSN has to do with the protocol used by MSN. This protocol was probably constructed in the era that we all trusted the internet and we could leave all ports wide open. To accommodate audio, MSN tries to open ports randomly and there is no way to control it. So if you use NAT you have to open all ports above 1024 and that is definitly not what you want. You could try a SOCKS4 proxy which is supported by MSN. SOCKS4 simulates your client to be directly connected to the internet for the particular application. That means that you have to abandon NAT and go for the Wingate Internet Client approach.
If you want to stay on NAT switch from MSN to Skype. That's what I did. Skype let you configure which port you want to use and that port setting is negociated when a connection is established. So I defined a small range of incoming ports on Wingate and gave every client its own "audio" port.
That really works neat.

Best regards,
Wim.

Thank you for your kind reply.
I heard about SKYPE but I have never worked with this application.
Unfortunately all my contacts work with MSN and I wish to study the best solution, or compromise to work with MSN.
I would like to solve with a right configuration of WINGATE if possible.

So, no guy of WINGATE TEAM can help me.
I can post, if necessary, some other details of my proxy configuration.
Please send me some comments.
