提交 Issue 之前请先阅读 Issue 指引，然后回答下面的问题，谢谢。
除非特殊情况，请完整填写所有问题。不按模板发的 issue 将直接被关闭。

1) 你正在使用哪个版本的 V2Ray？（如果服务器和客户端使用了不同版本，请注明）
v2ray-v3.21-linux-mips

2) 你的使用场景是什么？比如使用 Chrome 通过 Socks/VMess 代理观看 YouTube 视频。
打开网页和IM工具使用

3) 你看到的不正常的现象是什么？（请描述具体现象，比如访问超时，TLS 证书错误等）
iptables -t nat -N V2RAY
iptables -t nat -A V2RAY -d 192.168.0.0/16 -j RETURN
iptables -t nat -A V2RAY -p tcp -j REDIRECT --to-ports 12345
iptables -t nat -A PREROUTING -p tcp -j V2RAY
配置完上面四条iptables规则后，可以正常上境外网站，同时在路由器上可以dns解析，即ping baidu.com解析和响应正常

ip rule add fwmark 0x01/0x01 table 100
ip route add local 0.0.0.0/0 dev lo table 100
iptables -t mangle -N V2RAY
iptables -t mangle -A V2RAY -p udp -j TPROXY --on-port 12345 --tproxy-mark 0x01/0x01
iptables -t mangle -A PREROUTING -j V2RAY
iptables -t mangle -I V2RAY -d 192.168.0.0/16 -j RETURN
继续配置上面udp转发规则后，在路由器上ping baidu.com无法解析ip，ping 8.8.8.8正常，电脑上网使用ip的可以正常使用，需要域名解析的无法使用

4) 你期待看到的正确表现是怎样的？
在路由器和电脑上都可以正常解析dns

5) 请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。

7) 请附上访问日志。在 Linux 中，日志通常在 /var/log/v2ray/access.log 文件中。

    // 在这里附上服务器端日志

8) 其它相关的配置文件（如 Nginx）和相关日志。

9) 如果 V2Ray 无法启动，请附上 --test 输出。

通常的命令为 /usr/bin/v2ray/v2ray --test --config /etc/v2ray/config.json。请按实际情况修改。

10) 如果 V2Ray 服务运行不正常，请附上 journal 日志。

通常的命令为 journalctl -u v2ray。

请预览一下你填的内容再提交。

如果你已经填完上面的问卷，请把下面的英文部份删除，再提交 Issue。

同样的，dns通过tproxy转发到v2ray就打不开网页了，要串联一个pdnsd才行
