How to Configure Static NAT on Cisco Router

In this video, the presenter demonstrates how to configure static Network Address Translation (NAT) from scratch. They explain that NAT is used to protect internal IP addresses from hackers by translating private IP addresses into public ones. The setup involves using a 2911 router and connecting it to switches and hosts that will utilize private IP addresses. The presenter configures the LAN side of the router, sets up a default route, and identifies inside and outside interfaces for NAT configuration. They create static mappings for IP addresses, detailing the difference between inside local and inside global addresses, which are essential for understanding NAT. The presenter then tests the configuration by generating traffic and checking translation statistics to ensure the NAT process is functioning correctly. They conclude by emphasizing that servers can only see the public IP address, thus providing a layer of security against potential tracing by hackers. The video wraps up with a thank you to viewers for watching.
