Excellent! Thanks for the feedback. 👍
I tested every combination of bridges, vlans, qinqs and openvpns I could think of there and it looks good. There are a lot of possible combos though so let me know if you find anything.
One thing this exposed is that the bridge interfaces handling in FreeBSD 14 does a few things differently. The MTU setting especially has changed. Setting the MTU on the bridge should now propagate that to all members. And conversely it will override any setting on a member interface. So in the current snapshot you should find interfaces that are bridge members have the MTU field greyed out.
