PAT = Port Address Translation
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.
Hope this helps.
