This guide explains how to use Cloudflare to filter traffic from a specific country. This is useful for monitoring or blocking traffic from certain geographic regions.

Prerequisites

• A properly configured domain in Cloudflare.

Steps to filter traffic from a country

1. Log in to Cloudflare

1. Go to Cloudflare Dashboard.
2. Log in with your credentials.
3. Select the domain you wish to configure.

2. Navigate to Firewall Rules

1. In the side panel, click Security > WAF (Web Application Firewall).
2. Select Firewall Rules.

3. Create a new rule

1. Click Create a Firewall Rule.
2. Assign a name to the rule, such as: Filter Country - Italy.

4. Configure rule criteria

1. In the Field section, select Country.
2. In the adjacent column, choose the operator:
• is: to include only traffic from the specified country.
• is not: to exclude traffic from the specified country.
3. In the next field, select the desired country (e.g., Italy).

5. Set the action

Choose the desired action:

• Allow: Allows traffic only from the specified country.
• Block: Blocks all traffic from the specified country.
• Challenge (Captcha): Requires users to complete a CAPTCHA.
• JS Challenge: Verifies traffic with a JavaScript challenge.

6. Save and apply the rule

1. Click Deploy to activate the rule.
