Now the OPNsense system settings (logging, powerd, etc.), interfaces (VLAN + LACP), firewall rules, and CARP IPs are ready. The temporary IPSec tunnel to the remote Sophos is also online. ๐Ÿ˜

Setting up the 2nd OPNsense will take a bit more time, but thankfully I can sync all the firewall rules and so on from the primary to secondary.
