DESCRIPTION The stunnel program is designed to work as SSL encryption wrapper between remote clients and local (inetd-startable) or remote servers.The concept is that having non-SSL aware daemons running on your system you can easily set them up to communicate with clients over secure SSL channels.

I have a TCP Server/Client where the Server listens on port 5000 and the Client outgoing port is 39000. I have Stunnel set up on the Server: [custom] accept = 6000 connect = 5000 so it accepts connections on port 6000 and redirects it to 5000 (which my Server.c is listening on). I tried to set up STunnel on the Client in the following way: If there is a host-based Firewall (Windows Defender, McAfee, etc.) active on the server, ensure that you make an Inbound exception for the ports that Stunnel is listening on.

It is designed to work as an SSL encryption wrapper, encrypting the messages using industry-standard crypto libraries (such as OpenSSL) and allowing for secure communication without changing the program running on either side of the TCP connection. Configure stunnel to provide the client certificate to the LDAP server and configure your client to connect to stunnel. Ideally, you'll run stunnel on the same server(s) as your application and only listen locally so that you don't expose your LDAP directory beyond that server. Follow these steps: Install stunnel.
