If you host your own Noodle server please use a firewall.

The Noodle white list is a list of IP ranges that are allowed to connect to your noodle.

IP ranges are in the form of an ipv4 and a netmask.

If your settings are invalid Noodle will let everyone see the login page.

If you do something silly like 0.0.0.0/32 contact us and we can help you reset it with

update system_settings set value = '0.0.0.0/0', binary_data = null where key_name = 'WHITE_LIST';
service noodle restart

Only an internal network Example:

192.168.1.0/24

Only 2 IPs Example:

209.208.107.114/32
209.208.67.178/32

Everyone can see the login page Example:

0.0.0.0/0
