Configuration

Navigate to Config → System → Control admin access (/admin/config/system/control-admin-access)

Fill out the following two fields:

1. Field 1 - Enter IPs or IP ranges (Whitelist): Input the IP addresses or ranges of the computers to be granted access to the specified URL or URLs.

2. Field 2 - Enter URLs to block except for Whitelist: Specify the URLs of the pages to be blocked, excluding users specified in the first field.

For example:

In Field 1
192.168.1.10 (a single IP)
10.0.0.0/24 (an IP range)

In Field 2
/admin/settings
/user/1/edit

Users connecting from the specified IP addresses (whitelisted) will have unrestricted access to the entire site, including the specified URLs.

Users connecting from IPs outside the whitelist will be blocked from accessing the specified URLs, even if they are administrators or have other privileged roles.

This way, you can control and restrict access to certain parts of your Drupal site based on IP addresses. Adjust the IPs and URLs according to your specific needs and security requirements.
