As you can see from the RFC and John Mayes' article, NAT was originally designed to solve IP address depletion by changing IP addresses and was never intended to solve security issues. Private Internet Exchange, yes, the famous PIX firewall, was originally designed as a network translation device ( ). There was no concrete proof who invented Network Address Translation ( from now on, I will use the abbreviation, NAT), but the first ever commercially viable NAT device was created by John Mayes, Brantley Coile and Johnson Wu. Five engineers collaborated on a paper which became known as RFC 1287 ( ). In this article, I'll explain how NAT works on Palo Alto Networks firewall and hopefully it will be detailed enough to understand how to configure and troubleshoot NAT.īefore I started let's have a quick time travel back to 1991 and there was a discussion how to solve IP address depletion. ![]() Unless you are lucky ( or early ) enough to have a large pool of public/internet routable addresses, then NAT is your friend. NAT, a necessary evil, it's a love hate relationship between us, engineers and NAT.
