Thanks for your complete answer.
Anyway, I have two other things I need to get done, and then I'll be
back to revising my nftables patches, and incorporating Eric's firewalld
patches on top of that. If I can remember, If you want, I can Cc you
when I post new patches so you can try them out if you like.
Yes sure I can help to test this once ready.
Have a nice week-end
Hervé
