Correct.

The point of network-pre.target is that whatever network manager you
are using must be ordered After= it, so that your firewall setup can
be ordered Before= it and be set up correctly before any network
connectivity is established. This applies the same to NetworkManager,
systemd-networkd, or anything else.

Yes.

Cheers,
