Is it possible (and what will be the best approach) to restrict access to the Open edX LMS and/CMS instances to specific IP addresses (subnets or ranges)?
This is important mainly for admin and studio areas.
1- If user visited the website from allowed_IPs: He/she can access the web site
2- else (user comes from an IP not listed in allowed_IPs): Redirect them to a specific page ( “Access not allowed. Your IP is not allowed to access this website”)
