• WAN Users
These settings determine which packets are covered by the rule, based on their source
(WAN) IP address. Select the desired option:
• Any — all IP addresses are covered by this rule.
• Address range — if this option is selected, you must enter the Start and Finish fields.
• 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.
