NimbostratusI found out that this iRule actually gives the required information: when HTTP_RESPONSE { HTTP::header insert X-Internal [IP::client_addr] }
However im not sure its a standard header field, and now my question is, can i replace x-forwarder-for by this field? I mean when i get to the server the x-forwarder-for field instead of see my public IP the iRule will replace it to Internal IP and i will get x-forwarder-for: 192.168.10.1?

CirrusI'm not certain what you are doing with that iRule. [IP::client_addr] would return the client IP which would be the public IP address. And then you are inserting that IP address in a header going back to the client (since it's HTTP_RESPONSE event)?
Enabling x-forwarded-for in the HTTP profile will use the [IP::client_addr] value for that header. But you said that is providing the Public IP of the client, which makes sense since they are external customers.
