To whitelist an IP in WHM you need to log in using the `admin` user. From there you can search for 'ConfigServer Security & Firewall' in the left hand sidebar.
This page will show you the status of the server firewall and allows you to perform a number of actions.
To whitelist an IP:
- Scroll down to "csf - Quick Actions"
- The first section is called "Quick Allow". Enter the IP you wish to whitelist in the first box, add an (optional) comment, and click "Quick Allow".
- The IP is now whitelisted and can access all services on the server.
