WireGuard 内核模块式的加载, 效率非常高.
不过这东西是用UDP发送数据, 所以到了晚上就不会那么友好.

• 服务端和客户端:
官方支持: https://www.wireguard.com/install/ 第三方支持: https://tunsafe.com/download
• 部署:

wget --no-check-certificate -qO- 'https://moeclub.org/attachment/LinuxShell/wireguard.sh'| bash

• 说明:
1. 使用的是官方默认端口,端口为:51820.
2. WireGuard 需要 tun 设备才能正常工作.
3. 配置文件在 /etc/wireguard .
4. 配置文件 wg0.conf 为脚本自动生成的服务端配置文件.
5. 服务端已配置自启动, 启动服务命令.
   

   
   #配置文件为 wg0.conf 则命令中使用 wg0
   wg-quick down wg0; wg-quick up wg0
   

6. 配置文件 wg0-client.conf 为脚本自动生成的客户端配置文件.
   将其导入客户端即可使用.
7. 客户端配置文件中Endpoint项可以用域名代替IP地址.
8. 如果遇到错误请尝试重启,重新跑脚本.
9. 如果以下错误请尝试自行更换内核.
