PAT Description
Cisco 700 series routers provide PAT, enabling local hosts on a private IP network to communicate externally. 

Packets destined for an external address have their private IP address plus port number translated to the router's external IP address before the IP packet is forwarded to the WAN. IP packets returning to the router have their external IP addresses (plus port number) translated back to the private IP addresses and the packets are forwarded to the LAN.

When PAT is enabled, the transmission of RIP packets is automatically disabled to prevent a broadcast of the private IP addresses externally.
