Is there a Bug / Problem with NAT and ipfw on arm64?

You need to properly configure /etc/resolv.conf in your jail.
(In reply to Andrey V. Elsukov from comment #1) see in me first post: >/etc/resolv.conf (maihost + jail) > >nameserver 192.168.2.1
(In reply to Andrey V. Elsukov from comment #1) > You need to properly configure /etc/resolv.conf in your jail. Ah, I see, that you did that. But then check that it is reachable.
(In reply to Andrey V. Elsukov from comment #3) i think this is okay too: root@jail1icinga:/ # ls -la /etc/resolv.conf -rw-r--r-- 1 root wheel 50 Mar 14 09:52 /etc/resolv.conf
