Audio Chat issues with MSN Messenger over a router

[Guest]

Hi,

I recently loaded MSN Messenger 7.0 on my Windows 2000 Professional system.
This is a desktop that is connected to a Netgear Wireless router.

This router has uPNP enabled.

I am able to have text chats and am also able to see the web cam. But voice
chat always fails. I get an error that the remote network is experiencing
network difficulties. If I take my system off the router and connect it
directly to the broadband modem, everything is fine.


Any ideas on how to make this work?

Also, I am a novice in networking.. So, if you have any idea on how ports
can be enabled/disabled, it would be great !

Thanks and Regards
Girish

You can't. Some features require your machine to be directly on the Internet
with a Public IP#. You could do a one-to-one Nat from the NAT Device's
Public IP# back to your machine, but that would nullify the purpose of
having the NAT Device and would end up being the same thing as if you
connected the computer directly to the Internet with a Public IP# via a
Cable/DSL Modem.

I believe there are too many port ranges and random ports involved with the
Messenger to do this in any other way.

A NAT Device that has UPnP is supposed to be able to deal with this. I
don't use any and have no expience with using UPnP, but here is an article
on the subject.
