This app modifies the login logic to only allow logins from specified ip address ranges.
The allowed IP addresses have to be passed via occ app:config as a string
separated by comma.
For example:
To whitelist 127.0.0.0/24:
occ config:app:set limit_login_to_ip whitelisted.ranges --value 127.0.0.0/24
To whitelist 127.0.0.0/24 and 192.168.0.0/24:
occ config:app:set limit_login_to_ip whitelisted.ranges --value 127.0.0.0/24,192.168.0.0/24
To whitelist 127.0.0.0/24 and also 192.168.0.0/24 as well as 2001:db8::/32:
occ config:app:set limit_login_to_ip whitelisted.ranges --value 127.0.0.0/24,192.168.0.0/24,2001:db8::/32
Alternatively, you can use admin settings to restrict logins to specific ip address ranges.
