Hi, I think the firewall is not enable : --- iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination --- This is the output : --- ipvsadm -L -n IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 10.0.0.102:25 rr -> 10.0.0.96:25 Route 1 0 0 -> 10.0.0.97:25 Route 0 0 0 -> 10.0.0.98:25 Route 0 0 0 --- Just 10.0.0.96 is active.
