You can select whether the traffic will be logged. The choices are:

– Never — no log entries will be made for this service.

– Always — any traffic for this service type will be logged.

– Match — traffic of this type which matches the parameters and action will be logged.

– Not match — traffic of this type which does not match the parameters and action will be

logged.

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

in Figure 4-6, 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.
