What this post added

This post addresses a common customer pain point by expanding the range of supported web ports beyond 80 and 443 to include common control panel ports. While these ports are proxied, they do not undergo caching or performance transformations. The post also clarifies why non-web protocols like FTP and SSH cannot be proxied due to the lack of HOST headers, and highlights the security benefit of this limitation. It also mentions that traffic data from attempted attacks on these blocked protocols is fed back into Cloudflare's system for learning.
