Irule to see source IPs

Hello Kaladhar...you can do this 2 ways. First one is what Vitaliy and Nitass are suggesting - by using X-Forwarder if its a HTTP traffic and web server in the backend that needs to see the client ip.

The second option is by eliminating SNAT and using the F5 ip as your gateway for the servers instead of a switch. The second step involves in configuring your server network settings. The reason I am suggesting the second step is X-Forwarder will not work for non http traffic. I had a situation where the client address has to be seen by an application server and there was no way X-Forwarder would have resolved the issue.
