Stateful NAT requires kernel connection tracking. Stateless NAT does not, and is still a form of NAT. It's sometimes used in IPv4 networks, even!

- akira2501 4y agoDidn't you mean stateful NAT when you were making the comparison?
- greyface- 4y agoThat wasn't my intent, but I see how it reads that way now. The parenthetical was me griping about naming, not meant to update the meaning of the sentence. In the dual-upstream scenario, I'd use stateless NAT with a single on-link prefix (GUA or ULA).
