You can go to the faqs for each piece of software and they should tell
you which ports are required. I can give you one off the top of me head.

For netmeeting, you need to set your router up to allow ports 1720,
1503, 1731, 522, and 389 to the IP of the computer you are using for
netmeeting. This will allow video and making calls via the ILS servers
etc...Not sure what SMC menu allows you to do this but is commonly known
as "port forwarding". Neetmeeting faqs all over have this information
and can provide specific port details, i.e., what they are for...

For basic security reasons, if you are running more than one PC behind
your router, make sure you route those ports only to the IP(s) of the
PC's you need to use....
