WireGuard VPN：wg0.conf 不存在

Question

我正在尝试在 WireGuard 的帮助下在我的服务器上设置 VPN。我正在关注本教程https://upcloud.com/resources/tutorials/get-started-wireguard-vpn

错误

systemctl status wg-quick@wg0

我的行动：

文件 sudo nano /etc/sysctl.conf 中未注释的行

net.ipv4.ip_forward=1 

应用了以下更改

sudo sysctl -p

配置/etc/wireguard/wg0.conf

[Interface]
Address = 10.66.66.1/24,fd42:42:42::1/64
ListenPort = 58723
PrivateKey = XXXXX


PostUp = iptables -A FORWARD -i %i -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE;ip6tables -A FORWARD -i %i -j ACCEPT; ip6tables -t nat -A POSTROUTING -o eth0 -j MASQUERADE;

PostDown = iptables -D FORWARD -i %i -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE;ip6tables -D FORWARD -i %i -j ACCEPT; ip6tables -t nat -D POSTROUTING -o eth0 -j MASQUERADE;


[Peer]
# Client Name: Unnamed

AllowedIPs = 10.66.66.2/32,fd42:42:42::2/128

那我就开始WG

> wg-quick up wg0
wg-quick: `wg0' already exists

然后我启用 WG 自动启动

systemctl enable wg-quick@wg0

Answer 1

如果显示

wg-quick: wg0' already exists

，就运行

sudo wg-quick down wg0

然后：

sudo wg-quick up wg0
