NAT Terminology Disambiguation

This article is a part of a series on Network Address Translation (NAT). Use the navigation boxes to view the rest of the articles.
 
Network Address Translation

If you’ve made it here, then at this point you should have a solid understanding of each of the four types of translation that can exist: Static NAT, Static PAT, Dynamic PAT, and Dynamic NAT. Moreover, you have an understanding of Policy NAT and Twice NAT, which are simply two different ways of implementing the four types of NAT.

The definitions and examples provided in this article series encompass every type of address translation that can possibly exist. That said, for marketing efforts, most vendors use their own distinct terminology to refer to each type of NAT we have discussed.

The purpose of this article is to provide a single page which lists all the types of address translation and what each vendor calls them. In the future, each vendor term will also link to a configuration guide for that specific vendor’s syntax and implementation.

  1. Hi Ed,

    I came across your website, while looking for some answers. You have a wonderful way of explaining complex stuff in simple way. I have already read most of stuff on your site and looking forward for new series.
    Nat also is wonderfully explained.
