Port Address Translation (PAT) is a feature of a device that translates TCP or UDP
communications made between hosts on a private network and hosts on a public network. It
allows a single public IP address to be used by many hosts on the private network, which is
usually called a Local Area Network or LAN.
A PAT device transparently modifies IP packets as they pass through it. The modifications make
all the packets which it sends to the public network from the multiple hosts on the private network
appear to originate from a single host - the PAT device - on the public network.
In PAT, both the sender's private IP and port number are modified; the PAT device chooses the
port numbers which will be seen by hosts on the public network.
In PAT there is generally only one publicly exposed IP address and incoming packets from the
public network are routed to their destinations on the private network by reference to a table held
within the PAT device which keeps track of public and private port pairs. This is often called
connection tracking.
To configure Port Address Translation, move the cursor “>>” to pat and press enter.
