Replace X-Forwarded-For with X-Forward and that shouldl work.
You may want to update your Cisco ACE loadbalancing policy
map configuration to insert the standard X-Forwarded-For
instead of the X-Forward header by doing something like this
in Exec mode:
host1/Admin# show running-config policy-map
You should see something like this:
policy-map type loadbalance http first-match L7_LB_POLICY
class L7_LB_CLASS
serverfarm SERVER_FARM_1
insert-http x-forward header-value "%is"
Then just replace the header:
Host1/Admin# configure terminal
Host1/Admin(config)# policy-map type loadbalance first-match L7_LB_POLICY
host1/Admin(config-pmap-lb)# class L7_LB_CLASS
host1/Admin(config-pmap-lb-c)# no insert-http X-Forward header-value "%is"
host1/Admin(config-pmap-lb-c)# insert-http X-Forwarded-For header-value "%is"
host1/Admin(config-pmap-lb-c)# exit
host1/Admin(config)# exit
If everything works as expected just save your configuration and that's it:
host1/Admin# copy running-config startup-config
