Jeff,

 

Plz try to apply the below irule in PBN LTM /with SNAT and let me know the result.

 

rule X-Forwarded-For { when HTTP_REQUEST { if {[HTTP::header exists X-Forwarded-For]}{ HTTP::header replace X-Forwarded-For "[HTTP::header X-Forwarded-For], [IP::client_addr]" } else {

 

HTTP::header insert X-Forwarded-For [IP::client_addr] } }
