Introduction to NAT and PAT

Dear forum

How do i NAT my three Private IP to single public IP?

Hello Elias

In order to achieve what you are describing, you will need to apply Port Address Translation (PAT) sometimes called NAT overload. Take a look at this lesson:

Here you will see that there are two private IP addresses that are mapped to a single outside address. You can extend this configuration further for your requirement of three addresses. As you try out the configs in the lab, if you have any other questions please let us know!

I hope this has been helpful!
