Cloudflare Workers themselves don't directly dictate open ports on your origin server in the same way as the CDN. Workers execute at Cloudflare's edge. However, if a Worker makes an outbound request to your origin server, the connection will still attempt to use the standard ports (80, 443) unless explicitly configured otherwise.
