Hi All!
I have the same modem-router and MSN Messenger does not work for voice conversation. I can use text chat but not voice. When I try to Start Talking there is always a messege "Connecting to xxx's computer" and after that "Problem with network or other computer" or something similar. Everything OK with network and other computer. I tried to use old adsl modem with router, everything was fine.
I put the latest firmware, it does not help. I tried to make port forwarding - no success. Netgear DG834G support uPnP, so it should work without port forwarding. The only idea I could get is from MS web site: http://support.microsoft.com/default.aspx?scid=kb;en-us;826284&Product=WinMsgr
<i><b>SYMPTOMS</b>
If your computer is behind a network address translation (NAT) device such as a router or an Internet Connection Sharing computer that uses the UPnP service, and the static port range on your computer is set to use only one Session Initiation Protocol (SIP) port, you cannot log on to a server (such as a Microsoft Live Communications Server server) by using a real-time communications client (such as Microsoft Windows Messenger).
<b>CAUSE</b>
This issue occurs because two SIP ports are required when your computer is behind a UPnP certified NAT device.
SIP is a signaling protocol that is used to establish real-time communications sessions. To permit communication (sending and receiving data) between two computers, a port has to be opened on each computer. One of these ports is reserved for SIP traffic.
<b>RESOLUTION</b>
To resolve this issue, configure the computer that is operating behind the NAT device to grant a minimum of two SIP ports for signaling.

I don't understand a lot from that. Any ideas how to fix it?
Many thanks
