By default it's allow any to any, not just LAN subnet.  But if you
don't have a static route to that network, it'll get dropped by the
antispoofing rules (it couldn't return the traffic anyway since it
doesn't know how to get to that network on the LAN side).  Put in a
static route to that network behind the router, pointing to the
router's LAN IP and everything will work.
