 通过在主机上运行`tun2socks`，可以轻松地接管所有的`TCP/UDP`流量，同时提供诸多专业的功能特性，这包括：
 
 - 强制使不支持代理的程序走代理
-- 结合Clash、V2Ray等代理后端实现全局科学上网
-- 结合Burp、Charles等工具进行应用层数据的调试
-- 结合DHCP、CoreDNS等应用部署路由模式代理局域网流量

 ## 注意事项
 
 1. 由于采用了纯Go实现，所以这一版本的`tun2socks`在有大量连接时内存消耗通常较多。如果您的需求对内存消耗极为敏感，请继续使用 [v1](https://github.com/xjasonlyu/tun2socks/tree/v1) 版本。
