@nprofile1q... I know, but I don't think it's a good idea.
Imo clat itself should be deprecated.
It conflicts with the IPv6-only patch for Linux and other OS.
It has had its chance for more than 12 years. Instead we repair NAT64 gateways for the horror encapsulation of WiFi-calls and other things.
Has anyone tested, if CLAT starts in combination of nm+mm+mobile+ISP with IPv6-only (Telekom, EE, Bouygues)?
Iirc that still depends on RFC 7050.
