TrueNAS-12.0-U8.1 problems with tap interface

J

Jutzi

I am trying to install OpenVPN in an Iocage jail using these intructions: https://www.truenas.com/community/resources/openvpn-in-tap-bridge-mode-in-iocage-jail.85/

My release is FreeBSD 12.2-RELEASE-p14

Looks like handling tap interface in Iocage jail is somehow broken. Same kind of problems in the server itself, so the problem could be in FreeBSD.

This is what happens:

Code: 
freenas# ifconfig

Any help appreciated.
