| 9.3.3 |  | Destination NAT with the alias command |

| Dnat overview The alias command can also be used to perform destination NAT, or dnat . This is useful in situations such as that in the figure. The Web server in this example resides on the PIX Security Appliance DMZ and has an IP address of 172.16.0.2. Again, in order for hosts on the 10.0.0.0 network to access the Web server by its domain name, they must resolve the name by using the DNS server on the outside interface of the PIX Security Appliance. This presents a different problem, but one that can be solved by using the alias command.

| Media Activity Demonstration Activity: Enabling dnat In this activity, students will learn about configuring destination NAT on the PIX Security Appliance with the

alias command.
