Hi, I am having trouble using proxy arp with RH7.2 [linux 2.4.7-10 stock kernel which comes with it] Proxy arp doesnt seem to work. I have hosts a.stanford.edu and b.stanford.edu on the same subnet. b.stanford.edu is no longer there, and a.stanford.edu is set to proxy arp for it....so that it can get its packets [for a specific reason which is not so relevant here,hopefully]. i set the proxy arp entry in a.stanford.edu as follows: arp -Ds b.stanford.edu eth0 pub and then ping b.stanford.edu from some host outside. a tcpdump shows the gateway router doing an arp who-has b.stanford.edu but there is no arp reply at all from a.stanford.edu ?? can anyone tell me what i have missed ?
