Configuring MN-700 for Net Meeting

Hi,

I just recently purchased MN-700 Base station. So far very happy with the
ease of installation. Can anyone help me, or does anyone know how to setup
MN-700 to work with Net Meeting, will appreciate very much. So far without
any change in configuration, I have been able to send Net Meeting requests
out, but cannot receive one from someone outside.

I have tried enabling DMZ, as well as unsuccessfully tried to use port
forwarding based on MS's page on openning ports for NetMeeting.

I will appreciate very much.
