Re: X-Forwarded-For on L4 VS

Martin182 With the VS setup as an L4 VS you cannot manipulate any of the HTTP data which includes the HTTP header.

    Yes, that's what I was afraid of, there is no alternative to be able to deliver the real ip then?

      Hi Martin182,

      There are two possibilities to solve this:

      1. Configure the virtual server as standard and apply an http profile with x-forwarder-for " the most simple".

      2. Configure the F5 as a router with a couple of Virtual Servers 0.0.0.0/0 for TCP and UDP and make the Self-IP in the server's network of the F5, the default gateway for servers and avoid snat, it allows servers to reach outside through the F5.

      Hope it works.
