Ho,

But that does not account for the A ->[TLS] ->B part.

I believe that my sample will listen for unencrypted connection only.

You need to have a section in your config file which listen for requests but also have the “client = yes” option with a cert and key like this:

[http_a_to_c]

client = yes

accept = port_number_to_listen_on_server_b

connect = server_c_address:443

cert = certificate.crt

key = private.key

cert and key are the certificate and private key server B uses to identify itself on server C.

You could also add more options to specify a trustore to specify which cert coming from server C server B will trust, otherwise server B will simply allow the connection.

Good Luck

Consider scenario below:

Server A   ==TLS==> Server B  ==TLS+2WayAuth==> Server C

Server A needs to connect to Server C through Server B which runs Stunnel. Server C requires 2-way authentication. I have full control over Server A and Server B and Server C belongs to a third-party.

What does Stunnel config should look like?
