Static NAT Configuration

In this Static NAT Cisco Packet Tracer Configuration example, we will configure Static NAT on Cisco Packet Tracer. For our Cisco NAT (Network Address Translation) Config, we will use the below simple topology that has three routers. We will configure Static NAT configuration in the middle router.

We have three different NAT Configurations. These are:

• Static  NAT
• Dynamic NAT
• PAT

Here, we will focus on Cisco Static NAT Configuration on Packet Tracer.

With Static NAT is a type of NAT we map single private ip address to a single private ip address as one to one mapping. This is a manual ip address maping. For example, when we have an internal ip address 192.168.1.0, with Static NAT, we can map this ip address to 203.200.100.1 ip address. When ever a userr try to access 203.200.100.1 on Internet, it will route to 192.168.1.0.

Below, you can view Static NAT Cisco Packet Tracer Video.

We use Static NAT when an internal device needs to be accessible from the public internet at a fixed IP address. This behavior is also good for network security. Think about that, you have a web server which has ip address 192.168.1.1. Normally, you can not access this web server form internet with this private ip address. If you use Static NAT and map public to private ip address, you can access this web server with 200.100.3.1 ip address.

In this configuration, we have used the below key Cisco NAT commands. These are:

• ip nat inside
• ip nat outside
• ip nat inside source

Here, we have focused on Cisco Static Configuration and we will do this configuration with the help of Cisco Packet Tracer. For other NAT examples, you can view the other lessons to learn Network Address Translation better.

As a CCNA, CCNP or CCIE candidate, you can use Cisco Packet Tracer for these NAT Configurations.
