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.
Thx
Alex.
