That PPP is not ethernet. PPP runs at the IP layer. You probably should be using proxy-arp here, not bridgeing. proxy-arp is best described as a method for routing IP addresses within the same subnet. If you want to really bridge the two locations, for example, if you absolutely need to have the two locations in the same broadcast network or need to forward protocols not routable by Linux PPP then see for example vtund. If run with a TAP device (not TUN) then you should be able to bridge just as if the VPN connection was a local ethernet I think. Not that I have tried... Note: You most likely would want to run bridges at both sides of the VPN connection in such case, to filter what enters the tunnel from both ends.
