Inbound Rule Example: Allowing Videoconferencing
If you want to allow incoming videoconferencing to be initiated from a restricted range of outside
IP addresses, such as from a branch office, you can create an inbound rule. In the example shown
here, CU-SeeMe connections are allowed only from a specified range of external IP addresses. In
this case, we have also specified logging of any incoming CU-SeeMe requests that do not match
the allowed parameters.

Considerations for Inbound Rules
• If your external IP address is assigned dynamically by your ISP, the IP address may change
periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the
Advanced menu so that external users can always find your network.
• If the IP address of the local server computer is assigned by DHCP, it may change when the
computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu
to keep the computer's IP address constant.
• Local computers must access the local server using the computer's local LAN address
(192.168.0.11 in the example above). Attempts by local computers to access the server using
the external WAN IP address will fail.
