Configure the Cloudflare firewall

The firewall allows you to block visitors according to certain rules. Perform the following steps to create a rule:

1. Log in to ISPmanager as the User.
2. Go to Tools → Cloudflare → Firewall.
3. Select a parameter that the firewall will check in the Type field:
   • IP or IP range — Cloudflare will check the user IP address. Enter an IP address or IP range in the format "/". The supported prefixes are "/16" and "/24" for IPv4, "/64", "/48" and "/32" for IPv6;
   • Country — Cloudflare will check the user country. Enter a country code in the Source address filed. You can find a list of country codes at the Cloudflare website.
4. If the user parameter matches or is included in the range specified in the Source address filed one of the following Actions will be performed:
   
   • Allow — the visitor will always have access to the protected website;
   • Check — requires a user to complete a CAPTCHA in order to visit your site;
   • JS-check — during a JavaScript challenge you will be shown an interstitial page for about five seconds while Cloudflare performs a series of mathematical challenges to make sure it is a legitimate human visitor;
   • Block — visitor won't have access to the protected website;
   • Comment — optional field. Here you can add any information related to the issue.
5. Click on Ok to save the settings in Cloudflare.
