Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

NAT Masquerade in one picture posted April 2014

I wanted a recall on how masquerade worked in NAT, and I wanted a fast recall.

What's better than a picture? Nothing of course :D



Well done! You've reached the end of my post. Now you can leave a comment or read something else.



Thanks for this comprehensive single picture explanation, but I have a question: Why does the router change the packet's destination address? Why is the client's belief the destination to be false? I don't see a reason for this to occur without any further information available.
