Good luck there is nothing wrong with you CIPE VPN.  You just have to figure
out the routing.

If I ping (B) from (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.
