Thanks for speaking it out.
I already moved all my bridges and guests and virtuals to netgraph,
where I can find them again. It's much nicer to have a separate
plane of existance where one can put things together independent
from the ifconfig moloch.

>=C2=A0 =C2=A0 =C2=A0 =C2=A0And buggy, see [1]. Reported Oct. 2021 and s= till present.

Ups, is that a bug?
I got used to the scans sometimes either returning nothing or not
returning at all. The link itself now functioning, I thought this
an acceptable tradeoff.

cheerio,
PMc
