I have 10.241.0.0-15/16 bound to lo1 for jails, and I just realised it doesn't
work anymore. Boxes at $DAYJOB use the same config and work just fine on
11.1R/amd64, otherwise I'd be fired.... this used to work ~ 1 month ago, both
on my desktop, and my laptop, and now doesn't.
​Have I mis-configured something blindingly obvious here before I embark on a
lengthy bisect?
