Inbound Rule Example: Allowing Videoconference from Restricted Addresses
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
in Figure 7-4, CU-SeeMe connections are allowed only from a specified range of external IP
addresses.

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 Dyamic DNS feature in the
Advanced menus so that external users can always find your network.
• If the IP address of the local server PC is assigned by DHCP, it may change when the PC is
rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the
PC's IP address constant.
