Purpose

In this lab, we configured static network address translation in a network on Cisco Packet Tracer to translate the web server's local IP address to a public address.

Router Configurations

To start, we opened up the CLI for Router 1 and set the hostname to R1 for ease of referral.

Next, we configured and enabled the FastEthernet0/0 port and assigned an IP address of 10.0.0.1 with a subnet mask of 255.0.0.0.

Then we configured and enabled the Serial0/0/0 port and assigned an IP address of 20.0.0.2 also with a subnet mask of 255.0.0.0

Lastly, we set up IP routing from the switch to the serial port.

For Router 0, we performed similar configurations with a few additional specifications.

To test connectivity, we pinged the router addresses of 20.0.0.1 and 30.0.0.1 from one of the PCs in the network.

Static NAT Configuration

Next, we configured static NAT on Router 1 to be able to ping the web server using its NAT address of 50.0.0.1.

We first defined the FastEthernet0/0 port as the inside of the NAT network.

Then we defined the Serial0/0/0 port as the outside of the NAT network.

Finally, we created a static rule associated with the web server's private IP address and public IP address, respectively.

If configured correctly, you should now be able to ping the web server's private IP address of 50.0.0.1 as well as access it from a web browser.
