Dynamic NAT Configuration

In this Packet Tracer Dynamic NAT 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 Dynamic NAT configuration in the middle router.

We have three different NAT Configurations. These are:

• Static  NAT
• Dynamic NAT
• PAT

Cisco Packet Tracer Configuration Lab Course For CCNA and CCNP!

Here, we will focus on Dynamic NAT and its configuration. What is Dynamic NAT? Dynamic NAT (Network Address Translation) is a type of NAT where private IP addresses are mapped to public IP addresses from a pool. Here, ip address mapping is temporary and changes over time.

For example, if we have a private ip address 192.168.100.1 and we use dynamic nat, firstly, we define a public ip pool with public ip addresses 200.100.0.1-200.100.0.100. When the device connect to Internet, it gets a temporary ip address from this pool. For example, 200.100.0.15. After the session of the device, this public ip address returns to the pool.

Here one of the key point is temporary mapping. When needed, a public ip address is assigned to the device from the pool. And after the session end, it is returned to the ip address pool.

Below, you can view Dynamic NAT Configuration on Cisco Packet Tracer video.

In this Cisco Packet Tracer NAT lesson, we have configured dynamic NAT configuration. In another lesson, you can view Static NAT and PAT (Port Address Translation) configurations.

You can use this NAT config for CCNA, CCNP an CCIE certificaiton studies. To view the other videos, you can vview related lessons.
