On OUT
route add 10.0.0.0 netmask 255.255.0.0 192.168.0.4

Nope

Don't

In /etc/rc.conf, oops, /etc/defaults/rc.conf
static_routes="IN"
route_IN="10.0.0.0 -netmask 255.255.0.0 192.168.0.4"
That's on OUT, on IN just set defaultrouter to 192.168.0.1
The -netmask 255.255.0.0 is only needed if you are using something
other than 255.0.0.0 as the netmask on 10.0.0.0
And set gateway_enable="YES" on both.

Don't run it :)
