Environment : This feature was introduced only in 7.7.3 release of Airwave.
AirWave 7.7.3 introduced support for AMP whitelists. On the AMP Setup > Authentication page, you can now include
a list of subnets that are able to log in to AMP. If this option is enabled, then by default, the current client network will
appear as the first entry in the list of subnets. Additional entries can be added, one per line, in the text entry box.
This feature provided more security to Airwave server. When we provision IAPs on Airwave via internet, we will have to allow HTTPS access to Airwave's IP address. So anyone can reach the Login page of Airwave via port 443 over internet.
Once this feature is enabled, only the IPs/subnets listed in the whitelist would be able to access the GUI of Airwave.
NOTE: Just enabling this option auto populates the list with your machine's IP address ( x.x.x.x/32). if we do not change it before saving, GUI access will be blocked from all the IPs except one.
