Public web server has haproxy to allow users access to a lan server via custom port, url:port.
Problem is, this port becomes open and visible to public. Second problem is user can re-connect to this url:port any time without re-authentication.
What we need is;
-url:port should not be seen by public or cannot be accessed directly.
-user should have to log into an existing application in order gain access to the url and the app should give the user a cookie which expires immediately when the user is done or after a certain amount of inactivity.
Basically, we need a way to control access to the url:port combinations so that the user has to log into the existing app.
Your job would be to tell us what we need to do and I and a dev would set things up based on your input. We cannot give remote access but can use chat to communicate and solve the issue.
