openwrt r22 上，分享在两端配置 wireguard 虚拟网

[wuruxu]

由于机场有设备数量限制，而且 R1 路由器也可以申请到公网地址，所以就开了个端口，配置好 wireguard 服务, 然后可以把其他路由器的科学流量通过 dnsmasq 转发到 R1, 一起实现科学上网

R1 的地址配置为 192.168.111.1/24 和 fd08:ee99:dd11::1/80
其他客户端设备 pubkey 和地址地址，分别是 192.168.111.2 - 192.168.111.6 添加下面内容到 /etc/config/network

[e-mail]:~# cat /etc/config/network
