Select Language:If you’re trying to set up a security group to allow traffic from Cloudflare’s IP addresses, you might notice some challenges. ADVERTISEMENTLuckily, AWS offers a helpful feature: a security prefix named “com.amazonaws.global.cloudfront.origin-facing.” This prefix is maintained by AWS and is supposed to include the correct Cloudflare IPv4 address list. However, in my experience, relying solely on this AWS prefix didn’t work as expected. In your AWS Security Groups, create a new rule for inbound traffic. Save your security group rules.
