The remote end from board can do proxyarp - it can allocate an IP address
to the board to make it look as if it is on the same network as thew remote
end.
I knew there was something a bit funny with the ppp details you gave.
In my experience (which is using ppp over dialup modems - dates me
a bit!) usually on a ppp link the IP addresses of each end of the link are
on the same subnet. Yours are not. But then I'm not familiar with
data network over mobile connections.
