Inbound Rule Example: Allowing Video conferencing
If you want to allow incoming video conferencing 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 the following figure, 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 settings.
