PAT Configuration

In this Packet Tracer PAT Configuration example, we will configure Port Address Translation, NAT Overload on Cisco Packet Tracer. For our Cisco PAT Configuration, we will use the below simple topology that has three routers. We will configure PAT configuration in the middle router.

What is NAT? To learn the details of NAT, you can view the related NAT (Network Address Translation) lesson.  There different NAT types and here, we will focus on one of them.

What are the types of NAT? We have three different NAT Configurations. These are:

• Static  NAT
• Dynamic NAT
• PAT

Here, we will focus on Cisco PAT Configuration on Packet Tracer.

PAT (Port Address Translation) is also known as NAT Overload. It is a type of NAT where multiple private IP addresses are mapped to a single public IP address by using different port numbers to keep the connections distinct.

Here, we map one private ip address to one public ip address with a port number. Same public ip address is used for different devices with different port numbers. For example we have two devices and their private ip addresses are 192.168.1.1 and 192.168.1.2. We can use 200.100.100.1 public ip address with different port numbers for example with 1025 and 1026.

192.168.1.1 -> 200.100.100.1:1025 

192.168.1.2 -> 200.100.100.1:1026
