Freebsd should be using 255.255.255.0 as a default netmask for the
192.168 block as well. That's what it's defined to be. Changing that
means fixing it everywhere.
Also, as you get further from common setups, residential and soho
routers tend to get flakier. Given that most users of such don't have
hundreds of hosts and don't need two internal networks, a /23 in
192.168.0.0 qualifies as uncommon; it certainly gave me fits. I found
that splitting the /24 into a pair of /25s worked better.
