Hi.
Since I've upgraded to latest version of opnsense 24.1.4 gateway monitoring for wirguard stopped working after reboot. If I disable and enable WireGuard it works again just not after a reboot. I think I was on 21.1_13 before!
I didn't change anything in my config and everything was working ok
Any ideas why this might be happening? Routes and everything else work fine
EDIT:
Solved my own issue.
It looks like it was some static routes i had defined for the Wireguard addresses . I must have set up this a long time ago and didnt realize they were not required anymore.
