What I suggest you is :
- reduce the TCP port range like you did it and forward those ports.
Notice that those TCP ports are only used for compatibility with the
legacy Netmeeting. They are not used when communicating with other GM
clients.
- reduce the RTP Port range to 4 ports only, you absolutely need 4 ports
minimum
- reduce the UDP Port range to 2 ports.

It should work.
