How does PAT Work Cisco?
PAT allows you to support many hosts with only few public IP addresses. It works by creating dynamic NAT mapping, in which a global (public) IP address and a unique port number are selected.
What is PAT CCNA?
With Port Address Translation (PAT), one public IP address is used for all internal devices, but a different port is assigned to each private IP address. This type of NAT is also known as NAT Overload.
How do I set up PAT?
To configure PAT, the following commands are required:
- configure the router’s inside interface using the ip nat inside command.
- configure the router’s outside interface using the ip nat outside command.
- configure an access list that includes a list of the inside source addresses that should be translated.

Do home routers use NAT or PAT?
What Is NAT? NAT stands for network address translation. It’s a way to map multiple local private addresses to a public one before transferring the information. Organizations that want multiple devices to employ a single IP address use NAT, as do most home routers.
What is the difference between static NAT and PAT?
Static PAT is the same as static NAT, except that it enables you to specify the protocol (TCP or UDP) and port for the real and mapped addresses. Static PAT enables you to identify the same mapped address across many different static statements, provided that the port is different for each statement.
