  雷神OpenWrt插件安装建议:

  当前雷神路由器支持两种加速模式,
  1. tproxy加速模式(速度更快, CPU占用率更低)
  2. tun加速模式(需要依赖少, 安装灵活)
  
  需要您根据以上的加速模式, 安装对应的依赖库, 
  如下列出两种模式对应的安装依赖: 
  1. TProxy模式:  libpcap iptables kmod-ipt-nat iptables-mod-tproxy kmod-ipt-tproxy kmod-netem(可选) tc-full(可选) kmod-ipt-ipset ipset curl
  2. Tun模式:     libpcap iptables kmod-tun kmod-ipt-nat kmod-ipt-ipset ipset curl

  如何安装依赖:
  1. 升级依赖:   opkg update 
  2. 安装依赖:   opkg install xxx

  为了安装方便, 请选择一个模式, 复制以下命令到终端运行: 
  Tproxy模式: 
  opkg update 
  opkg install libpcap iptables kmod-ipt-nat iptables-mod-tproxy kmod-ipt-tproxy kmod-netem tc-full kmod-ipt-ipset ipset

  Tun模式:
  opkg update 
  opkg install libpcap iptables kmod-tun kmod-ipt-nat kmod-ipt-ipset ipset curl

  关于steamdeck的支持说明
  steamdeck设备请选择加速电脑游戏
  
  关于手机设备的支持:
  1. 安卓支持说明 
  当前代理仅支持ipv4代理, 请更改dhcp配置，更改完配置请重启路由器，
  配置路径在 /etc/config/dhcp 
  config dhcp 'lan'
    ... 此处是一些其他配置
    ra 'disable'
    dhcpv6 'disable'
    list ra_flags 'none'
    ... 此处是一些其他配置

  2. 关于ios设备的支持说明
  ios设备, 安装完插件后, 为了精准识别, 请在ios上选择忘记wifi, 然后重新连接即可
