proxyarp tells the PPP server to answer ARP requests on it's local
ethernet port on behalf of the remote system. This permits you
to take an address from your local LAN to use on the remote end
of the PPP connection without worrying about routing from the other
systems on your LAN (including your border router, etc). ARP
is of course the IP address discovery protocol and is used to
map physical addresses to TCP/IP addresses.
defaultroute is used on the client side. The PPP daemon setups
up a default tcp/ip route via the PPP connection after establishing
the connection. This is just a route add default command, but
since the PPP daemon knows the addresses at both ends of the connection
it can assign the route easily and automatically. Don't use this
unless you want all non-local TCP/IP traffic forwarded over the
link, of course.
