Windows Messenger - NAT - Firewall issues

[Carey Wise]

I have a Netgear MR814 router with a built in firewall,
am having trouble getting voice and video to work from
inside my network. The router has the latest firmware
which now includes UPnP support. By default it is set to
a 30 minute advertistement window with a 4 hop time to
live. I always want to initiate the voice or video from
my computer, not accept when initiated from the outside.
When i try to initiate a voice or video connection from
my Windows XP pro system it says "connecting to
*usernames* computer" hangs there for about 30 seconds
and then fails. I am trying to avoid at all costs
placing my system into the DMZ as it basically negates
the firewall. Is there a current list of ports that must
be opened even if the call is initiated from inside the
firewall? Thank you for any help i can get

It is probably the ports configuration. I dont know the ports because i dont
use the video feature however if you do set the ports to be forwarded
through to your computer then other video users on your network will no
longer be able to use it. Thats how i would understand it.
