I already know how NAT traversal works, and I've read a lot about it before.
But credit to David Anderson at Tailscale. Their NAT traversal article is excellent, the best I've seen on the topic: https://tailscale.com/blog/how-nat-traversal-works/ https://tailscale.com/blog/how-nat-traversal-works/
- pjkundert 5y agoThanks for that! I hadn't heard, before, that anyone had successfully used the "Birthday Paradox" on port numbering to successfully defeat NATs. Glad to see that Tailscale has successfully implemented and tested this -- not just at one layer, but at multiple layers of NATs!
