I'm pretty sure this has the same cause as #254343 , which is a vtnet bug, not a jail or bridge bug.

Having recently upgraded to 13.0-STABLE, I found that none of my jng-enabled jails were coming up after boot. root@puroto:/ # service jail start pupuru Starting jails: cannot start jail "pupuru": ngctl: send msg: Operation not supported jail: pupuru: jng bridge pupuru vtnet0: failed . root@puroto:/ # In this case the jails.conf entry was: pupuru { exec.prestart += "jng bridge pupuru vtnet0"; exec.poststop += "jng shutdown pupuru"; } Digging into what jng was doing, we were trying to switch the parent interface to promiscuous mode, failing, and then bailing out: # ngctl msg vtnet0: setpromisc 1 ngctl: send msg: Operation not supported Just commenting out that line in jng seemed to be sufficient, though I don't know what side effects that might have. My jails all came up ok after that, and were at least able to send/recv traffic, ping the jail host, etc. 306 # Set promiscuous mode and don't overwrite src addr 307 # ngctl msg $iface: setpromisc 1 || return 308 ngctl msg $iface: setautosrc 0 || return I checked that my copy of /usr/sbin/jng wasn't significantly different to the one being shipped in /usr/share/examles/jails.
