[Bridge] kernel doesn't support bridge with a ppp interface ?

I'm not sure if this is even possible using standard protocols. Bridging is
for Ethernet; PPP is not Ethernet. So this would require some sort of
nonstandard Ethernet-over-PPP encapsulation protocol, and would only make
sense if the PPP devices at both ends of the link talked this protocol.
This sounds like a job for something outside the kernel, e.g. OpenVPN as
suggested or a simpler Ethernet-over-IP tunnelling app.
