Lab – implementing dynamic NAT

In this lab, you will learn how to implement dynamic NAT with a pool of IP addresses. The following network topology shows an organization network (left) that is connected to the internet via the ISP router:

Figure 9.19 – Dynamic NAT topology

The objective of this lab is to allow the IP addresses of devices in the company attempting to communicate on the internet to be translated to an available public IP address, via dynamic NAT, on the HQ router.

Please be sure to use the following guidelines when creating this lab to ensure that you get the correct results:

  • Assign the IP addresses as shown in the preceding figure to each device accordingly.
  • Each router (Cisco 2911 model) interface must be configured as shown in the topology.
  • Configure each end device with the corresponding IP address, subnet mask, and default gateway, as shown in the topology.
  • Configure a default route on HQ to point to...
