You may need to open aa.bb.cc.197 and aa.bb.cc.198 on other interfaces too,
on B.
Also, the full routing tables could help, but I suspect you don't have a
default route on A, or have a default route not pointing to the right
interface.

 ppp is a point to point protocol. local is the address of the local end
 of the link, remote of the remote end of the link, from the host's view
 (so local and remote are inversed on the other end of the link).

on B, yes. But on A it won't set up the default route if you don't tell it to
do so. It's independant from proxyarp.
