Whitelist Cloudflare’s IP addresses

Once you’ve changed your name servers to Cloudflare, web traffic will be routed through Cloudflare’s network. Hooray! This means that your webserver will see a lot of traffic proxied through Cloudflare, and in order to allow all this traffic to access it, you will need to make sure that Cloudflare IPs are whitelisted and not rate-limited in any way on your server (you can ask about this at your host). We have a page with all the CloudFlare IPs.
