The route for the local subnet looks like your above result and is
normally added automatically when the interface is configured. It
sounds like you're trying to add the new host's default route so it
can communicate beyond the local subnet; if not, please excuse me and
explain your environment in more detail is possible.
Assuming that the address assigned for the new host is 192.168.254.x,
you probably want the following if manually configuring while running.
Substitute "ed0" with the appropriate name of your NIC.
$ ifconfig ed0 inet 192.168.254.x netmask 255.255.255.0
$ route add -net default 192.168.254.254
Or automatically in /etc/rc.conf:
ifconfig_ed0="inet 192.168.254.x netmask 255.255.255.0"
defaultrouter="192.168.254.254"
