Everything is on subnet 192.168.0.nnn/8, *except* the new firewall, so I
set *just* my computer (this box, FBSD 9.3p2) to the 192.168.111.nnn/8
subnet using ifconfig. I could indeed reach the firewall through my
simple switch (Netgear from Best Buy). However, when I set this box
*back* to my usual subnet, nothing past the router (which the firewall
is intended to replace) worked w/o a reboot.
