The webserver logged the BIGIP IP addresses (192.168.1.157)
instead of Client IP Address.
Anything wrong in my configuration.. Please advise.. Thanks

Wes_98712You are SNAT'ing your external VLAN, that will cause all source IP addresses to look like your external SNAT. Remove that and the client IP's will stay static.
David_Sherman_2I know this answer is late (5 months+...)
Anyway, looking at your config, I think the problem is that you are attempting to insert a http header in to an encrypted packet. This will not work. The only way to insert the header with the source IP is to have the F5 terminate the ssl session, then insert the header and then have the F5 re-encrypt or send it unencrypted back to the web server.
