Are you talking about bridging or routing? If the former, yes but
with some work (ie, kernel patches). If the latter, just edit rc.conf
to enable IP forwarding and set up your routes. You don't need routed.

FreeBSD doesn't do that stuff.. it has some vestigial code in the
kernel but nobody uses it and it's disabled by default.
