Hello.  I use socat to connect stunnel to a socks proxy on my client workstation running windows.  the socks proxy then connects to a news server on the internet. The initial connection works just fine and it appears to stay connected while I am transferring data and for a while afterwards; but after a period of idle connection say five or ten minutes, I get a message from my network adaptor popup saying that the connection stunnel had to my localhost has failed.  Any ideas on how I can make the connection between stunnel and localhost persist longer during periods of inactivity? I would like it to stay connected until I purposely stop it. Below is the relevant section of “stunnel.conf”.

accept = 127.0.0.1:120

connect = 127.0.0.1:5630
