I'm running ROS 3.x on a RB450. Hotspot is up and running on one of the interfaces. Another interface goes out to the Internet via cable modem. A third interface is set up with the 10.x.x.x network for servers, etc.
I would like to configure the hostpot network so a custom page (with graphics) is displayed as the login page. The only entry field on the login page should be an email address field. Whatever the user enters there would be stored somewhere and the user logged in (regardless of what they entered).
I have a Windows http server on the 10.x.x.x network configured as a walled-garden for the hostspot network, so users can get there before login.
Any suggestions on how to show the custom login page? E.g. put the whole login page on the RB450 vs the Windows server? How should I capture the email address from the login page - I assume on the Windows box, not the RB450...
I don't need exact instructions, just an overview (e.g. put the login page here, redirect there, write a script to do whatever, etc.)
