This is my Load Balancer CSS11503 configuration

MY load Balancer works fine only when one server is active that is server 2 but when i activate the server 1 and 3 i am not able to reach any of the server the iOS version is sg0810106 (08.10.1.06) please let me know if you need more detail, waiting for your responce.

Thanks..........

first, start by removing the command 'port 80 range 88' from all services.

The behavior of this command is most probably not what you think.

Then, since you are in one-armed mode, you need to guarantee that the server response goes back to the CSS.

One easy way is to add the following commands to your config

group clientnat

vip address 10.138.79.41

add destination service Server1

add destination service Server2

add destination service Server3

active

Let me know if this works.

Also be aware that you have not configured stickyness but source ip hashing loadbalancing.

This is different.

You may want to use 'balance roundrobin' with 'advanced-balance sticky-srcip'.

Gilles.
