Thanks Barry
I did what you suggested
1. Removed that two iptables rules.
2. IP Forwarding was already enabled.
But still Its giving same error.
In this case Iam trying to connect the IP of virtual server.
Is ther any thing wrong in my configuration. ?
The way Iam testing is not correct, If it is So.. What is the correct way to test the setup
Please Help me out
Thanking You
Laxman
