(The other is down right now, = so I can't get to it.) For some reason the following was in /etc/rc.conf=20 (I don't know if that was done by setup or some other program): network_interfaces=3D"l0 xl0 xl1" I changed that to: network_interfaces=3D"lo0 xl0 xl1" and now the box activates lo0 on boot, including the ipv4 address. I'll have to check the other box tomorrow morning.
