How to see the real IP in server- The traffic is from VIP:HTTPS and SNAT is enabled.

If NAT is applied, you are no longer able to see the IP of original source host in TCP-level information at the end-server.

However, Since it's a HTTP(s) service, you can achieve that with the use of HTTP headers. You can instruct F5 to insert the x-forwarded-for HTTP cookie which contains value of the real source IP. This setting can be enabled in Profiles > Services > HTTP_PROFILE_USED_BY_SERVICE

• Enable the "Insert X-Forwarded-For" setting
