1.安装

sudo apt update
sudo apt install wireguard

2.生成本机key

wg genkey | tee privatekey | wg pubkey > publickey

3.配置

这里分服务端配置以及客户端配置

a) 服务端配置

[Interface]
Address = 192.168.33.1/24
MTU = 1420
PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -A FORWARD -o %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -D FORWARD -o %i -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
ListenPort = 39900
PrivateKey = {本机私钥}

[Peer]
PublicKey = {接入机器公钥}
AllowedIPs = 192.168.33.99/32

b) 客户端配置

[Interface]
Address = 192.168.33.2/32
PrivateKey = {本机私钥}

[Peer]
PublicKey = {服务端公钥}
Endpoint = {服务端公网ip}:39900
AllowedIPs = 192.168.33.0/24
PersistentKeepalive = 25

4.配置文件位置

常见位置：/etc/wireguard
有时候也在：/usr/local/etc/wireguard

一般来说修改其中的wg0.conf就可以了

# 快速启动
sudo wg-quick up wg0
# 快速关闭
sudo wg-quick down wg0

5.直接使用客户端
