安装

从 https://github.com/Lochnair/vyatta-wireguard/releases 下载对应的包
ERL, ER等 mips架构的，下载 octeon 版本
ERX 下载 ralink版本。

可以选择上传到路由上，或者ssh登录路由，sudo su到root，执行类似如下的命令

curl https://github.com/Lochnair/vyatta-wireguard/releases/download/0.0.20170612-2/wireguard-octeon-0.0.20170612-2.deb -o wireguard-octeon-0.0.20170612-2.deb

1	curl https://github.com/Lochnair/vyatta-wireguard/releases/download/0.0.20170612-2/wireguard-octeon-0.0.20170612-2.deb -o wireguard-octeon-0.0.20170612-2.deb

或

curl https://github.com/Lochnair/vyatta-wireguard/releases/download/0.0.20170612-2/wireguard-ralink-0.0.20170612-2.deb -o wireguard-ralink-0.0.20170612-2.deb

1	curl https://github.com/Lochnair/vyatta-wireguard/releases/download/0.0.20170612-2/wireguard-ralink-0.0.20170612-2.deb -o wireguard-ralink-0.0.20170612-2.deb

下载完成后

dpkg -i xxx.deb

1	dpkg -i xxx.deb

配置

执行下列命令生成私钥、共享密钥，公钥

wg genkey > /config/auth/wg.private
wg genpsk > /config/auth/wg.psk
chmod 0600 /config/auth/wg.*
wg pubkey < /config/auth/wg.private

wg genkey > /config/auth/wg.private

wg genpsk > /config/auth/wg.psk

chmod 0600 /config/auth/wg.*

wg pubkey < /config/auth/wg.private

将最后一个命令的输出复制下来，配置到服务器端

获取服务器端的公钥，替换下文的“公钥”并执行命令

configure
set interfaces wireguard wg0 address 192.168.10.40/24
set interfaces wireguard wg0 listen-port 本地端口
set interfaces wireguard wg0 peer 公钥 allowed-ips 0.0.0.0/0
set interfaces wireguard wg0 peer 公钥 endpoint '服务器IP:端口'
set interfaces wireguard wg0 peer 公钥 preshared-key /config/auth/wg-eos.psk
set interfaces wireguard wg0 private-key /config/auth/wg.private
set interfaces wireguard wg0 route-allowed-ips false
commit
save

configure

set interfaces wireguard wg0 address 192.168.10.40/24

set interfaces wireguard wg0 listen-port 本地端口

set interfaces wireguard wg0 peer 公钥 allowed-ips 0.0.0.0/0

set interfaces wireguard wg0 peer 公钥 endpoint '服务器IP:端口'

set interfaces wireguard wg0 peer 公钥 preshared-key /config/auth/wg-eos.psk

set interfaces wireguard wg0 private-key /config/auth/wg.private

set interfaces wireguard wg0 route-allowed-ips false

commit

save

配置好设备后，配置nat服务

configure
set service nat rule 5032 outbound-interface wg0
set service nat rule 5032 type masquerade
commit 
save

configure

set service nat rule 5032 outbound-interface wg0

set service nat rule 5032 type masquerade

commit

save

剩下就是配置路由规则了，可以参考我的其他blog.

安装WireGuard

按照官方说明，可以使用下列命令装依赖，不够的自己看着装

apt-get install libmnl-dev linux-headers-$(uname -r) build-essential pkg-config

1	apt-get install libmnl-dev linux-headers-$(uname -r) build-essential pkg-config

直接从git里拉。

git clone https://git.zx2c4.com/WireGuard

1	git clone https://git.zx2c4.com/WireGuard

直接make就行

cd WireGuard/src
make
make install

cd WireGuard/src

make

make install

配置

参考前一篇文章“WireGuard wg-quick PostUp的高级玩法”，可以直接无视官方和其他各种第三方给的教程。

前文给了一个参考的配置。

[Interface]
Address = 192.168.10.1/24
MTU = 1500
PrivateKey = xxx
PostUp = echo -n "hello" > /dev/udp/192.168.1.1/80; echo -n "hello" > /dev/udp/192.168.2.1/80
 
[Peer]
PublicKey = xxx
AllowedIPs = 192.168.10.40/32, 192.168.1.0/24
Endpoint = 2.2.2.2:12345
 
[Peer]
PublicKey = xxx
AllowedIPs = 192.168.10.50/32, 192.168.2.0/24
Endpoint = 3.3.3.3:12345

[Interface]

Address = 192.168.10.1/24

MTU = 1500

PrivateKey = xxx

PostUp = echo -n "hello" > /dev/udp/192.168.1.1/80; echo -n "hello" > /dev/udp/192.168.2.1/80

[Peer]

PublicKey = xxx

AllowedIPs = 192.168.10.40/32, 192.168.1.0/24

Endpoint = 2.2.2.2:12345

[Peer]

PublicKey = xxx

AllowedIPs = 192.168.10.50/32, 192.168.2.0/24

Endpoint = 3.3.3.3:12345

按上述配置，假定的网络环境如下：
服务器：IP 1.1.1.1，WireGuard内网 IP 192.168.10.1，公网环境
节点1: IP 2.2.2.2，WireGuard内网 IP 192.168.10.40，LAN IP 192.168.1.0/24
节点2: IP 3.3.3.3，WireGuard内网 IP 192.168.10.50，LAN IP 192.168.2.0/24

此处，服务器、节点1、节点2均有公网IP。

如果节点IP不固定，或者是没有公网IP，那就改为如下配置

[Interface]
Address = 192.168.10.1/24
MTU = 1500
PrivateKey = xxx
ListenPort = 54321
 
[Peer]
PublicKey = xxx
AllowedIPs = 192.168.10.40/32, 192.168.1.0/24
 
[Peer]
PublicKey = xxx
AllowedIPs = 192.168.10.50/32, 192.168.2.0/24

[Interface]

Address = 192.168.10.1/24

MTU = 1500

PrivateKey = xxx

ListenPort = 54321

[Peer]

PublicKey = xxx

AllowedIPs = 192.168.10.40/32, 192.168.1.0/24

[Peer]

PublicKey = xxx

AllowedIPs = 192.168.10.50/32, 192.168.2.0/24

VPS上，将配置文件保存为 /etc/wireguard/wg0.conf，执行下列命令，启用Wireguard：

wg-quick up wg0

1	wg-quick up wg0

为了让网络正常工作，还需要在VPS的公网接口上启用NAT

iptables -F FORWARD
iptables -A FORWARD -j ACCEPT
 
iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE

iptables -F FORWARD

iptables -A FORWARD -j ACCEPT

iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE

修改 /etc/sysctl.conf，启用 ‘net.ipv4.ip_forward=1‘，然后执行 ‘sysctl -p‘

接下来是大招

真的很高级。

wg-quick是WireGuard用来启动网络设备的**脚本**。

注意了，迄今为止，wg-quick是用bash写的一个脚本，不知道未来会不会变，至少目前shebang是

!#/bin/bash
