Hi
x-forwarded-for header is a concept of Layer 7 and
DNAT Layer 4 concept. if you are running in dnat mode you always (http
and https) will see the ip of the client that is doing the request through the
load balancer to the backends.
If you're trying try to read
the x-forwarded for header you will see the ips that
managed the connection (proxys or web servers) please read more about
x-forwarded for header (http://en.wikipedia.org/wiki/X-Forwarded-For)
if you're working with https connections the proxys or web
servers can't decrypt the request for modifying the x-forwarded-for
header, for this reason you don't see the ip in x-forwarded-for header for
https connections.

Hi,
I have configured a L4TxNAT profile (with DNAT option) to load balance 8
back-end proxy servers for internet browsing.
I need to know original client IP in the proxy server as one of the security
requirement for tracking purpose.
I am able to see the client ip address from X-forwarded-for (XFF) header for
http sites browsed by end users, but I cant see it for HTTPS sites. For https
sites it shows LB ip address as source IP.
Can someone clarify and let me know how to get client's ip addresses in proxy
server for both http and https sites browsed by end users?
Thanks in advance
Deepak.
