Are you sure unbound listen on 127.0.0.1? What a %sockstat | grep unbound shows? Mine: unbound unbound 527 3 udp6 ::1:53 *:* unbound unbound 527 4 tcp6 ::1:53 *:* unbound unbound 527 5 udp4 127.0.0.1:53 *:* unbound unbound 527 6 tcp4 127.0.0.1:53 *:* unbound unbound 527 7 stream /var/run/local_unbound.ctl unbound unbound 527 8 stream -> ?? unbound unbound 527 9 stream -> ?? > It doesn't appear to be working that way for us :( > > -Kp > _______________________________________________ > freebsd-questions@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to > "freebsd-questions-unsubscribe@freebsd.org" --- --- Eduardo Morras <emorrasg@yahoo.es>
