Perhaps I've resolved my own problem. I created a .config for my server 
mode and another for my client mode in /etc/stunnel

I also changed /etc/init.d/stunnel4 back to ENABLED=0

I also note a typo error in my first post. The other file I edited was 
/etc/default/stunnel4 rather than /etc/default/stunnel I left ENABLED=1 
as is in that file. I don't know if what I have done is correct but my 
logs are showing successful connects to both my server configurations 
and my client configurations.

I am baffled with one thing though. I note that when running one config 
file I have 6 stunnel4 processes showing in my System Monitor and when I 
run both config files I have 12 processes. Is the normal for some reason???
