I just compiled a 2.6.16.1 kernel and installed iptables 1.3.5 and CLUSTERIP is still not responding to ARP requests. Am I missing something here? iptables -A INPUT -i eth1 -d 192.168.0.10 -j CLUSTERIP --new --hashmode sourceip --clustermac 01:23:45:67:89:AB --total-nodes 2 --local-node 1 echo "+2" > /proc/net/ipt_CLUSTERIP/192.168.0.10 Robert LeBlanc
