+# About stunnel
+# --------------------------
+#
+# The network looks like this:

+#   From the client's perspective:
+#
+#   |------- stunnel client --------------|    |---------- stunnel server -----------------------|
+#    consumer app -> localhost:accept_port  ->  connect:connect_port -> ??
+#
+#   From the server's perspective:
+#
+#   |------- stunnel client --------------|    |---------- stunnel server -----------------------|
+#                                       ??  ->  *:accept_port -> localhost:connect_port -> service
