Limit app access to local network
-
I'm looking to enhance the security of an application by adding an additional layer of access control. Currently, I have a LAMP stack with Adminer installed for database management. To prevent unauthorized access, I keep Adminer disabled most of the time. However, I would like to set it up so that Adminer can only be accessed when I am connected through a VPN. This would ensure that even if the service is running, it remains secure from public access unless I'm using the VPN.
