Just as a note using netgraph (with jng script as a workaround) works.... Also manually creating a bridge in the domu and adding xn0 as a member makes this fail.... so the issue is indeed related to the bridge. I'll open a PR later in case someone want to look into it, but I'm happy it works with netgraph.
