Website does not load after using X-Forwarded-For HTTP header

Hi ,

you say that SSL is terminated on the backend and not on the F5. Therefore the BIG-IP cannot insert any HTTP headers.

Please see K4816: Using the X-Forwarded-For HTTP header to preserve the original client IP address for traffic translated by a SNAT object

Quoting from there:

"Note: You can insert HTTP headers in HTTPS traffic only if the client connects to a BIG-IP virtual server configured with a Client SSL profile. When the BIG-IP system terminates the SSL connection, it has access to the unencrypted HTTP data."

You can only insert a X-Forwarded-For header once you make your virtual server capable of performing SSL decryption/encryption. For details see: K12015: Configuration requirements for SSL virtual servers, profiles, pools, and monitors.
