I have 10.241.0.0-15/16 bound to lo1 for jails, and I just realised it does=
n't work anymore. Boxes at $DAYJOB use the same config and work just fine o=
n 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.
=E2=80=8BHave I mis-configured something blindingly obvious here before I e=
mbark on a lengthy bisect?
