Polycom VSX7000 Behind Router/Firewall with Port Forwarding

The Polycom VSX 7000 can function perfectly well from behind a NAT firewall router with port forwarding enabled accordingly.  I was able to get ours to work very quickly by configuring the video conference device as follows:

• Login to the Web interface for the device.  The default login credentials for the Polycom VSX7000 is username "admin" and the password is the full serial number of the device.
• Go to the Network > IP Network portion of the menu, and see the Firewall section of the page.
• Settings should be:
• Fixed Port, yes apply check mark.
• For TCP & UDP Ports: enter 3230 as the starting values.
• Under NAT Configuration, specify manual.
• Specify NAT Public (WAN) Address, as the Internet IP of your firewall router device.

On your Router / Firewall, configure Port Forwarding for the following range of ports  to the LAN IP of your Polycom.

• 3230 to 3235 TCP & UDP
• 1720 TCP & UDP
