2. Whitelist an IP Address

Step 1: Log In to WHM

Log in to WHM using the root account.

Step 2: Open ConfigServer Security & Firewall

WHM

Plugins

3. Additional Options

Quick Deny

The Quick Deny option can be used to block an IP address from accessing the server.

Quick Ignore

The Quick Ignore option also allows an IP address, similar to Quick Allow, but with different behavior.

  • Quick Allow: The IP address is whitelisted. However, it can still be blocked later if it triggers ModSecurity rules or exceeds the allowed number of failed login attempts.
  • Quick Ignore: The IP address is excluded from blocking. It will not be blocked by ModSecurity or LFD (Login Failure Daemon), even if it triggers security rules or repeated login failures.
