SSL/TLS Offload

If the virtual webserver uses https, and the real webserver http, the WAF offloads the SSL/TLS. But what happpens if you configure the real webserver with https as well? Does the WAF just act as a passthrough, sending everything to the real webserver, or does it still offload by decrypting the initial data between client and UTM and then re-encrypt between UTM and real webserver?

  • If the idea is to offload the SSL processing from the web server to the UTM, then the Real Server will NOT be defined as HTTPS.

    I'm not sure why you would have a separate, internal certificate for the physical server.
