Interesting.  Can you put another Web server box outside of Untangle to
decrypt the traffic, then pass it through as normal?  That could help with
performance as well.  Or use a second network connection to pass the traffic
back out to Untangle's external interface?

Also, do you find that stunnel is able to work reliably doing HTTPS in this
way?  My recollection is that there is some difficulty with redirects
generated by the Web server, but perhaps something has changed.

Good luck!
