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 3-6, 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.
