Computer Networking Lab | Port Address Translation (PAT)
In this video, I will demonstrate Port Address Translation (PAT) using a simulated cloud scenario. In the scenario, addresses within the 10.0.0.0 network represents a private network and all other network addresses represents public networks.
End devices within 10.0.0.0 must have their addresses translated into public addresses. Using PAT, these end devices will be translated into 3.3.3.0 network devices via Router 1.
**Note: RIP is being used but the R1 and R2 are connected routers. Therefore, their routing tables have the necessary information for packet forwarding.
