 Routing only works if you have a remote PPP peer in a different IP
 subnet. Then, you do not need proxyarp, but you need routing.
 In this scenario, I have a LAN subnet, called, with the PPP
 server address The remote PPP peer dials in via VPN, and picks
 up an IP address ( from the LAN subnet. This one requires
 working proxyarp. Without proxyarp, LAN hosts cannot reach the remote
 PPP peer, as they have a network route for this subnet on their LAN
 interface, and won't go to their default gateway.
 In a perfect world all WAN connections should use Layer 3 routing.
 Actually, the world is not perfect - I cannot change the topology -
 and it used to work this way for more than 15 years.
