If you have it configured on both sets of LTMs then (assuming that no other device in the middle changes it) there will be two X-Forwarded-For headers and the first one will have the client's IP. The second LTM shouldn't change the header unless you configure it to. It sounds like you only should configure that header to be inserted on the set of LTMs that can see the client IP.
