udp2raw或者phantun这种faketcp工具支持吗

[resticDOG]

服务端是华为云 ECS 主机，使用 udp2raw faketcp 协议伪装了 wireguard，由于 ECS 无公网 IP, 使用一个 BGP 的公网 IP 转发了 udp2raw 的端口， 服务端开启 fakehttp

客户端上海联通，使用 udp2raw 和转发后的公网 IP 成功建立连接，wireguard 也能成功连上，fakehttp 在握手的时候也能看到 FAKE(*) 日志，但是依然未能突破限速：

所以很疑惑，是不是通过端口转发之后就失效了，必须有公网 IP 的网口监听才有效果，请各路大佬解答，感谢🙏
