Netmeeting uses a large range of ports and my be a security hazard opening the many required ports. It may be better at this time to just put computer in DMZ during Netmeeting session.

This is what MICROSOFT has to say....

»support.microsoft.com/support/kb···6/23.asp

--------------------------

MS Netmeeting is a router-unfriendly application simply because of that fact that it uses dynamic ports - meaning that every time the application is opened, it is using different ports to operate. Hence, this application does not work well behind any NAT firewall. Some customers have been able to get this application to work by opening up all the ports for certain triggers.

This is definitely not recommended by SMC, but we can provide you with the information these customers have given us. Beyond this, there is nothing else that can be done. If this info does not solve your problem, please contact Microsoft.

----
Triggers = 389, 522, 1503, 1024, 1720, 1731
Incoming ports (the same for all triggers) = 1-64535

All the ports are TCP. You can also try putting your machine in the DMZ (through Misc. Items) and make sure that you have upgraded the firmware on the router.
