are there OTHER networks on the WAN accessed via B's gateway/router ?
network A's gateway is the internet route?
if B's gateway has routes to the rest of 10.x.x.x, I'd just define a
static route like 10.0.0.0/8 -> B's gateway/router's IP, and leave the
DEFAULT gateway as network A's internet/DMZ router.
