If I ping 10.0.0.1 (B) from 10.0.1.2 (D), I'm pretty sure the
internet is not going to route it for me. I also saw the
packets on the cipb0 and ppp0/eth0 interface.

As long as D does not send something to B, B can't send something
to D because of the NAT. Once D does send something, things work
perfectly. Although, I'd like to use DNAT for it.
