Hi Adrian, I had a similar issue this morning! my issue was that I didn't have an iRule to notify the backend servers that the traffic was SSL offloaded by the F5.

 

I was reading this article about setting up ssl offloading;

 

https://www.lullabot.com/articles/setting-up-ssl-offloading-termination-on-an-f5-bigip-load-balancer

 

And in that article it included instructions on setting up an irule with the following code:

 

##

# Notify the backend servers that this traffic was SSL offloaded by the F5.

##

when HTTP_REQUEST {

HTTP::header insert "X-Forwarded-Proto" "https";

}

 

Once I did that, my SSL Offloaded VS started to work. I'm still having issues with some redirects, but at least I can get to the correct destination now.

 

Hope this helped.
