# opnsense-patch https://github.com/opnsense/core/commit/311184daa8
# /usr/local/etc/rc.filter_configure
It should bring back the required anchors.
Cheers,

Quote from: OPNenthu on January 30, 2026, 05:42:54 PMUPDATE: to close the loop, I was able to bring the bridge interface down with 'nmcli conn down br0', but the inverse 'nmcli conn up br0' returned success and never actually brought it up.There are a couple more nmcli options I see mentioned in the man page : Maybe try those too ?
I followed up with 'nmcli device up br0' and this timed out (failed).
I then used the GUI toggle switch for the parent interface (which was already up in 'ip a' but showed as down in the GUI) and it brought it back up.
However the same toggle switch does not bring the br0 interface down :P
So it's quite an inconsistent mess. Probably either a Mint / Ubuntu bug, or my configuration is just too complex or I set it up incorrectly.
