If the machine is in the DMZ, the port should be reachable from the
outside without any problem. As long as you can not telnet to port 1720,
you won't be able to call from GM to NM (as basically GM is doing a sort
of telnet). However, I don't have any idea how we could help you with
this unfortunately :(

Have you checked that the machine running Netmeeting (ie not the one
doing the NAT) has its firewall disabled completely?
