Hi,

The proxyarp option of pppd seems to be unrelated to the proxy_arp option
provided by the kernel. The following definitions will make it clearer.

-----
Proxyarp (in pppd)
              Add an entry (pppd does it!) to this system's ARP [Address
Resolution Protocol] table with the IP address of the peer and the Ethernet
address of  this system.   This will have the effect of making the peer
appear to other systems to be on the local ethernet.
-----
-----
proxy_arp (kernel)
        proxy_arp for the interface will be enabled if at least one of
conf/{all,interface}/proxy_arp is set to TRUE, it will be disabled
otherwise. Routers use it to answer ARP queries on behalf of hosts who are
unable to do so.
