Router A has ed0, on the office net, and ppp0, to router B. Router B has ed0, on the home net, and ppp0, to router A. Router A has proxy-arp entries for all hosts on the home net, and a route for all those pointing to its ppp0. Router B has routes for all hosts that aren't on the home net pointing to its ppp0, and ARP_PROXYALL. (This is just a guess =) If some of the hosts on the home net are mobile, then router A has to be able to dynamically delete its proxy entry. (Although due to a subtle bug, I think that the proxy entry will be modified to have the machine's real address when you turn it on on the office net, so the real requirement is for A to dynamically re-establish the right proxy entry when the host leaves the office net).
