I will keep this suggestion, and look at those. Thanks!
And it seems i have forgotten some stuff from my Alpine posting in
December, hmm. I had looked at

This i have not done. In fact i misused the mail for thanking
the kernel guys, i am sure they will all read it. Maybe i should
have sent it to the netfilter list, i have searched for "bug" on
the ML overview page.

Yours too. Thanks!
