Port Address Translation Now that you've learned NAT, we can explore Port Address Translation (PAT). We discuss at length the purpose for PATs, what their use empowers us to do and why. You'll learn the cost effectiveness of rather than purchasing one address for each network and why it's more management and cost effective to use the 1st address in the NAT pool and how the router tracks and manages this info in its NAT table.
