Huh? They _must_ be on different subnets. You can't route one subnet
across multiple network interfaces. Besides, a router always knows
how to route packets between its own directly-attached networks, no
additional routes are necessary.
The problem here is that a route needs to be added for 192.168.10.0/24
-> 192.168.0.100 in the upstream router(s), since the upstream
router(s) do not currently know to send any packets destined for
192.168.10.0/24 to 192.168.0.100 for delivery. The upstream router is
currently sending these packets to its own default gateway, which is
likely even further upstream. IP routers aren't mind-readers, you
have to tell them exactly where to send packets, but usually that is
very simple.
Running a routing protocol (such as RIP) on both the FreeBSD box in
question and the upstream router(s) would automatically add the same
route for you, but that is unnecessary in such a simple network
configuration.
