#nat66 — Public Fediverse posts

Networking equipment maker #Unifi is late to the #IPv6 game.

The first thing I come across is, that they build #NAT66 support which is neither standardized nor needed.

Why?

with internal #NAT66 DNAT and SNAT in an unwholesome combo.

All network engineers, in sympathy:
"I understand. I weep, but I understand."

After toiling for a few hours, I've managed to achieve a working #Palworld server on my #IPv6only #k8s cluster. The server is responsive on both modern and legacy IP, which I think might be fairly unique, since the game server doesn't listen on #IPv6 and I suspect the game client doesn't connect on IPv6 either.

This works using a Tundra-NAT64 CLAT sidecar, doing #464XLAT, with internal #NAT66 DNAT and SNAT in an unwholesome combo.

Occasionally, it pays to have a strong networking background.
