ConfigServer Security & Firewall (CSF) allows you to manage your iptables configuration. CSF is a simplified interface that makes it easy to add or remove IP addresses from your firewall. This process can whitelist an ip, removing any blocks if there is one.

  1. To Whitelist an IP address you must log into your WHM interface with your credentials.

  2. Go to “ConfigServer Security & Firewall". (you can search for it in the searchbox)

  1. Once you have reached this page go to ‘Quick Allow’ and type in the IP address you wish to whitelist.

  1. Press ‘Quick Allow’.

Most of the options are explained, but to configure a firewall, there are three options that are most important : Quick Allow, Quick Deny, and Quick Ignore. Simply enter the IP address into the coloured box, and left click the ËœQuick Allow", ËœQuick Deny" or ËœQuick Ignore".

Once this is completed this will allow this IP address to both access your server and websites located on the server.
