Port Forwarding - Cisco UC320W Configuration Manual

Port Forwarding

In its role as a router, NATing between LAN and WAN interfaces, the UC320W also
acts as a perimeter security device with firewalling enabled. The Port Forwarding
screen of the UC320W Configuration Utility allows the administrator an opportunity
to expose specific application ports to the "outside" WAN interface. This is typically
done to allow external users to access servers on the inside of the network, such as
port 80 for Web server services.
The administrator may configure port forwarding and then click Next, or skip this
task by simply clicking Next.
