Firewall rules may be set up to deny requests based on a variety of factors, including IP addresses, user agents, and certain activities.
  • IP blocking: Cloudflare enables website owners to prevent traffic from a certain IP address. Error Code 1020 will appear if you try to visit the website if your IP address has been banned.
