That doesn't seem to make much sense.  I assume you want FBSD to be .1
since you want to use it as a router.

ifconfig ed0 inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255

It can also be set in /etc/rc.conf.  Look for ifconfig_ed0=""

Yup, remake with:

pseudo-device	bpfilter	4

in the kernel config file.
