Lines: 10 Proxy ARP can be used for all routing, not just subnet routing. The idea is to give your hosts default routes that tell them to treat everything as on the local cable. This is done in Unix by doing route add 0.0.0.0 YOURADDRESS 0 where YOURADDRESS is the Internet address associated with your Ethernet interface (if you have more than one, the one you want used as default). By using a metric of 0, you tell the system to treat this route as on the local cable, so it issues ARP's rather than using a gateway. It is of course possible that some TCP/IP implementations don't have an equivalent kludge, but many of them seem to.
