Lab – implementing static NAT with port forwarding

In this lab, you will learn how to implement static NAT on an organization router to forward traffic that is originating from the internet to an internal private server. This exercise is an extension of the previous lab. We'll be using the following topology and the same guidelines as before:

Figure 9.14 – Static NAT with port

The objective of this lab is to allow users (Public PC) on the internet to access the internal web server on the private corporate network via NAT. Therefore, when the Public PC enters the public IP address into the web browser, the HQ router will translate and forward the traffic to only the internal web server.

To implement static NAT with port forwarding, use the following instructions:

  1. Configure the inside interface on the HQ router that points to the internal web server:
    HQ(config)#interface GigabitEthernet 0/1
    HQ(config-if)#ip nat inside
    HQ(config...
