title: Cannot establish connection to application listening on 0.0.0.0:8443
body: <p>I have an application that is listening on 0.0.0.0:8443 (local address). <br/><br/>
  "netstat -ant" output: <br/><br/>
  proto||Recv-Q||Send-Q||Local Address||Foreign Address||State<br/>
  tcp||0||0||0.0.0.0:22||0.0.0.0:<em>||LISTEN <br/>
  tcp||0||0||0.0.0.0:8443||0.0.0.0:</em>||LISTEN</p>
  
  <p>These are the only two ports that are listening.  When i telnet localhost port 22 and 8443, both are able to connect. But when i telnet from another computer on the same subnet, i am able to connect to port 22 but not port 8443.  The host and client computer are only connected via a switch.  What could be the cause?</p>
