• Single address — enter the required address in the Start fields.
•Log
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.
