The one I published earlier is intended for proxy only. Are the clients connecting via the same interface which is sending & receiving the proxy arps? Normally, you use proxy-arp'ing to connect NAT'ed IPs to public IPs you want to forward the traffic to. If you are not using NAT, but bridging, normally then the clients can ARP for themselves.... -- -Chuck
