due to NetMeeting assigning ports dynamically.)

Netmeeting ports:

389 LDAP.
636 Secure LDAP over SSL.
1503 T.120 teleconferencing protocol.
1720 H.323 call setup.
1731 Audio call control protocol.

This is only partially correct. These instructions are for opening firewall ports. You are also running NAT. Since the router uses your ip address and each computer is then assigned an internal ip address, you have to rout each port through the router to the correct machine manually. I've read many places that this is possible but most routers I've tried only allow about 10 forwarded ports. This is fine if you need to just forward 1 for a server of FTP but not enough for video conferencing. I've not been able to figure out how to do it and finally gave up. I couldn't even get it to work from a machine on DMZ. The DMZ machine goes through firewall clean but still doesn't get the correct ports forwarded to it through the NAT. If you get this to work please tell me how you did it.

The only way I can think of that would allow you to have 3 machines use netmeeting from behind a firewall is to setup your own ILS server and have it on the DMZ. ILS software comes standard with WinNT4 and Win2K server CD. I dunno it can be installed on Workstation though.

I tried dmz but it doesn't hack it.I'm gonna to assign ip manually to that laptop (right now uses dchp) and see what happens.
But thats after xmas.
Merry christmas everybody.

You need to open them ports for Netmeeting and portforward the external IP to the appropriate computer/internal IP.

If you are using a generic router then try this:

Server Rules:

Portforward: 216.151.100.123 10.10.x.x tcp_389
Portforward: 216.151.100.123 10.10.x.x tcp_636
Portforward: 216.151.100.123 10.10.x.x tcp_1503
Portforward: 216.151.100.123 10.10.x.x tcp_1720
Portforward: 216.151.100.123 10.10.x.x tcp_1731


Ipchains/Iptables:

Portforward:"0/0 10.10.x.x -d 216.151.100.123 -p tcp_389 tcp_636 tcp_1503 tcp_1720 tcp_1731"


eg.
0/0 = From Any IP.
10.10.x.x = Internal IP.
-d = Destination.
216.151.100.123 = Anandtech External IP (firewall IP).
-p = Protocol.
_xxx = Port number.
