搬家后电信取消了我的ipv4的公网ip，搞得我所有依赖公网ip的服务全部失效了。 于是我在休息了一阵后开始捣鼓恢复的事情。

　　首先得需要的是一个有公网ip的服务器，我是在腾讯云上买的，轻量云服务器，2核1G 峰值带宽320mbps 每个月40左右，然后使用GIthub上开源的 WG 安装脚本： Github

bash
curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
chmod +x wireguard-install.sh
./wireguard-install.sh

按照脚本执行即可，贴一下我自己的配置：

config
[Interface]
Address = 10.66.66.1/24,fd42:42:42::1/64
ListenPort = 49198
PrivateKey = -
PostUp = iptables -I INPUT -p udp --dport 49198 -j ACCEPT
PostUp = iptables -I FORWARD -i eth0 -o wg0 -j ACCEPT
PostUp = iptables -I FORWARD -i wg0 -j ACCEPT
PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostUp = ip6tables -I FORWARD -i wg0 -j ACCEPT
PostUp = ip6tables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D INPUT -p udp --dport 49198 -j ACCEPT
PostDown = iptables -D FORWARD -i eth0 -o wg0 -j ACCEPT
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT
PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
PostDown = ip6tables -D FORWARD -i wg0 -j ACCEPT
PostDown = ip6tables -t nat -D POSTROUTING -o eth0 -j MASQUERADE

最后使用各设备客户端连接就行。
