Dynamic NAT Lab

Dynamic NAT Configuration

In this tutorial we are going to learn how to configure Dynamic NAT which is shown in the following topology given below;

Now we could see the topology given above and to get the green light connection in all we will be studying through screen shots. Which is shown with clear explanation to understand this concept.

To assign IP address in Laptop click Laptop and displays in our screen then click Desktop  

click IP configuration and Select Static  

Now we can set IP address as given in above table.

Run following commands to set IP address and hostname.

Router R1 :

Same way access the command prompt of R2 and run following commands to set IP address and hostname.

Router R2 :

That is all initial IP configuration we need. Now this topology is ready for the practice of dynamic NAT.

R1 Dynamic NAT Configuration

For testing purpose I configured dynamic translations for two addresses only.

On R2 we can keep standard configuration or can configure dynamic NAT as we just did in R1 or can configure static NAT as we learnt in pervious part of this article.

Let’s do a quick recap of what we learnt in previous part and configure static NAT on R2.

R2 Dynamic NAT configuration

Testing Dynamic NAT configuration

To test this setup click Laptop0 and Desktop and click Command Prompt.

> Run ipconfig command

> Run ping 200.0.0.10 command

> Run ping 192.168.1.10 command

Therefore, we have completed our Dynamic NAT configuration with the help of cisco packet tracer version 7.0.
