Securing the Adobe Connect Pro Web Application (HTTPS only) with Stunnel (Alternative to using OpenSSL)


You would like to use a third party appliation to secure your Adobe Connect Pro Licensed Web Application Server (6x, 7x).


1. Download the stunnel windows installer here:

2. Install stunnel on the same box as Connect.

3. Insert the following code in the custom.ini without replacing or deleting any existing text:




4. Copy your certificates and private keys to the root of the stunnel install.

5. Rename the original stunnel.conf in the root install directory of stunnel and create a new copy containing the following:

; Protocol version (all, SSLv2, SSLv3, TLSv1)

sslVersion = all

; Some performance tunings

socket = l:TCP_NODELAY=1

socket = r:TCP_NODELAY=1



; Service-level configuration (you can put as many of these as you want in here)


; incoming vip for https (This is to secure Web)

; ip address that resolves to the ConnectProHost (Web App FQDN).

; listens on port 443

accept =

; When stunnel is on the same box, simply leave the below IP address as

; send the unecrypted request to port 8443

connect =

; Certificate information for Connect.

; This assumes you put the cert and key in the root folder of stunnel

cert = CertificateNameHere.pem

key = CerificateKeyNameHere.pem

6. From the Start / Programs Menu, find Stunnel and select "Install Service". If you have a passphrase on your private key, you should remove it.  You can do this by running a simple command within OpenSSL 

7. Start stunnel service. 

8. Start the Connect Services
