根据实验发现，在shadowsocks服务端开启监听udp会导致udp被封，但tcp一直正常，且直接传输udp包容易遭遇qos

If you are proposing a new protocol change, please open an issue in https://github.com/shadowsocks/shadowsocks-org and standardize it.

On the other hand, you could first make a POC program and see if it could actually solve your problem.

我之前新开了一台vps，ss里设置了tcp_only，就这样持续了两个星期后依然正常，然后我又改成了tcp_and_udp，3天内就被封udp了；为了排除是突然开启udp导致的，一个月后我又在同一IDC下买了vps，直接在ss里设置了tcp_and_udp，仍然在3天内就被封udp；后来又在其它IDC下买vps，直接在ss里设置了tcp_and_udp，仍然在3天内就被封

不过奇怪的是，即使设置了tcp_and_udp，导致udp被封，但tcp依然一直正常

This is quite a special case.

ip被墙了现在靠着v2插件cdn模式苟活，不支持udp over tcp确实难受现在考虑要不要换到v2或者xray那边去了。

如果你用了2022系列加密的话，部分客户端支持uot(如clash-meta和sing-box)，shadowsocks rust服务端也能自适应

谢谢不过用不上了，我使用了这个 https://github.com/heiher/hev-socks5-tunnel 再用ss的隧道功能就能实现UDP over TCP了

老哥 你是怎么配置hev-socks5-tunnel 与 shadowsocks 的sslocal 的tun 的了? 我尝试很久都不能成功
