A Business Communications Manager has two LANs and a WAN. The WAN connects to an
Internet Service Provider that assigns the IP address. The LANs are part of a private network. The
system maps all outgoing traffic. HTTP traffic is mapped to 10.10.10.4. LAN1 subnet is
10.10.10.0, LAN2 is 10.10.11.0.
The rules would be as follows:
Default Rules: Enabled Including IP Phones
