Passing true Source IP to backend server.

I received a request from my server team for some of their servers. They want, or are required, to see the true source IP rather than the Big IP self-IP. I'm thinking I need to use an x-forward, is this right?

 

What is the best way to do this?

 

Thanks.

    You are correct!

     

    HERE is a link to the documentation.

     

    Lots of people use the iRule rather than the HTTP profile, but I believe the latter is more efficient as far as CPU cycles go.

     

    Hope that helps! If it does, please up-vote and select this answer, it would be greatly appreciated
