  • I guess the issue can be the reverse proxy ;-)

     

    are you sure the reverse proxy is not configured to remove existing XFF header?

     

  • Hi,

     

    Best friend is Wireshark/tcpdump. Capture client traffic on DMZ LTM and then between DMZ and DC LTMs and you will see what's going on.
