Inbound Rule Example: Videoconferencing From Restricted Addresses; Considerations For Inbound Rules - NETGEAR FVL328 Reference Manual

Inbound Rule Example: Videoconferencing 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 5-5, 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 menus so that external users can always find your network.
• If the IP address of the local server 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 computers' local LAN address
(192.168.0.11 in the example in
server using the external WAN IP address will fail.
