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?
