DLNA (10.6.2) doesn't work in TrueNas Jail

[marquisexb13]

Problem description

DLNA doesn't seem to work for TrueNas jails in 10.6.2. No DLNA server appears on my network despite enabling DLNA, restarting, entering various entries in LAN address, etc.

I thought perhaps it was my install (FreeBSD 11.4), but I tried a clean install into a new jail (12.2) and am having the same issue.

Steps to reproduce

Not much to do. Follow the instructions for FreeBSD install, enable DLNA, add the LAN address, open VLC & no DLNA?

Try airsonic-advance

[marquisexb13]

Tried that as well. Couldn't get it to install in freebsd (see: https://www.reddit.com/r/airsonic/comments/omtss5/is_airsonicadvanced_possible_in_truenas_jail/)

Also tried it in Docker, and that didn't work either...

Found something quite interesting. If I run the war with java (java -jar airsonic-10-6-2.war) UPNP/DLNA works!

Running from java:

This is from a machine run with tomcat (notice the bolded line never occurs...)
