Q: After you enable an Internet connection firewall, how do you get NetMeeting to continue to work?
For NetMeeting, one or more of TCP ports 1731, 1720, 1503, 522 and 389 need to be opened for the program to work properly. The exact ports to be opened will depend on the NetMeeting configuration on the desktop. You can manually open ports using the following steps:
1. Click Start, and then click My Network Places.
Note If the Settings button is unavailable, ICF is not enabled on this connection and you do not have to open any ports (they are all already open).
5. Click Add to open a new port.
NOTE: You can specify the IP address of an internal computer; however, in most cases, you use 127.0.0.1.
For information about other applications that may require ports to be opened with ICF, please read Microsoft Knowledge Base Article 307554
