Example: Port Forwarding for 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 6-4, CU-SeeMe is a predefined service and its 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.

Example: Port Forwarding for VPN Tunnels when NAT is Off
If you want to allow incoming VPN IPSec tunnels to be initiated from outside IP addresses
anywhere on the Internet when NAT is off, first create a service and then an inbound rule.
