CGNAT Front Cover_for_web.jpgCGNAT, which is also known as Large Scale NAT, is a buzzword for a highly-scalable NAT device that sits between the CPE and a core network. If the device being used is an MX Series, well now, that device is very scalable, and it can take your current Network Address Translation usage and truly make it carrier grade. It’s all in how you set up the MX. What you need is a JTAC engineer to explain the ins and outs of the MX Series, and that’s what Joe Naughton does in this book. He provides the configurations, the feature sets, the application layer gateways, and the syslogs you need to make the MX hum. There’s a troubleshooting chapter written as only a JTAC engineer can, as well as a scalable use case that puts some load balancing MX features to the test. However you define CGNAT it begins with MX.

Great book!

Notice: this book is all about NAT on the MS-DPC card. The newer MS-MPC & MS-MIC cards do not support several of the configurations and features (such as PBA) discussed here (at least as of now).

Good question about MS-MPC cards.

What about MS-MPC cards ? Have you more information about this cards ?

Hello Magog,


We do have regular techpubs docs around the newer MS-MPC and MS-MIC cards but I have not written a second edition of this specific guide for the newer cards yet. A lot of the basics and foundations of this guide can help but I understand why an edition focused on the newer cards is desired.

Hi joseph When do you plan to release a new book with these new cards?

Hello  Joseph


Excellent book


Nevertheless it will be useful that the new book covers the new cards and features, like AMS interfaces.



Thanks for your time writting this book
