A Windows GUI wrapper (written in C#) around the CFnat tool, which automatically finds and tests Cloudflare datacenter IPs and sets up local port forwarding to the best-performing ones. It targets users on networks with unstable anycast routing to Cloudflare, such as China Mobile and China Broadcasting networks.

Use cases

• find the fastest cloudflare ip for my network
• optimize cloudflare ip routing on windows
• screen cloudflare datacenter ips by latency
• set up local port forwarding to cloudflare ips
• fix unstable anycast routing to cloudflare
• pick best cloudflare colo like hkg or sjc
• generate a cloudflare preferred ip list

When to choose

• you are on Windows and want a graphical interface for CFnat without using the command line
• your ISP (e.g. China Mobile or China Broadcasting) has unstable routes to Cloudflare anycast IPs
• you want to filter Cloudflare IPs by datacenter, latency, and TLS port and forward local traffic to them
• you need prebuilt binaries for x86, amd64, and ARM including Windows 7

When to avoid

• you need a supported, officially endorsed tool for production or commercial use - the project explicitly disclaims support and liability
• you are not working with Cloudflare IP optimization or port forwarding
• you require a maintained product with technical assistance - the author provides none
• your use case may be restricted by local laws - the project is stated to be for educational, research, and security-testing purposes only
