[stunnel-users] Inbound and outbound connection on same PC?

Hi, I have a linux PC that now successfully runs a stunnel client connection with a remote server. I now want to be able to access sql server on that linux PC from a remote Windows PC. What I would like to gather information on: 1. Can the client configuration of stunnel on the linux PC be used for a second connection from the remote windows PC to access data (sql server)? 2. Thus, what differentiates a client from a server - a server can have multiple connections and provides data? A client can't? 3. What is the correct route I should take? Regards,
