Yes. All of the directives that do _not_ mention enp1s0 "take". What's annoying is that all this worked before upgrading to 11.7 .. and I'm positive of that because this is a server running bind that now dies on the query-source-v6 address xx::yy port *; line in named.conf :( Is there a way to get systemd to do <this> list of commands in /etc/sysctl.d/something.conf and <that> set of commands in /etc/sysctl.d/somethingElse.conf _after_ all the interfaces come up? Thanks Lee
