使用WireGuard为阿里云专有网络主机提供外网访问

前言我的阿里云服务器网络处于混合过度模式，逐步从经典网络往专有网络迁移。之前每台经典网络主机都申请了公网IP和带宽，实际上对于大多数主机的业务而言，并不需要对外提供网络服务，只需要能访问外网即可。所以这次新加的主机部分都没有去加弹性公网IP。于是带来了问题：内网主机如何访问外网？阿里云的dnat方案太贵了。不考虑。尝试过本地配置网关，但是实验证明，阿里云的VPC交换机不是一个纯粹的二层交换，也许是设计有问题，也许是刻意阻止用户自己拿一台能访问公网的主机当内网网关。所以这次使用WireGuard实现网络架构调整。阿里云的经典网络主机里加了几条默认的路由：

10.0.0.0/8
172.16.0.0/12
100.64.0.0/10

10.0.0.0/8

172.16.0.0/12

100.64.0.0/10

前两个都好说，第三个是运营商级的NAT网络地址，之前在 OpenVPN Site-to-Site VPN between Asus Merlin And Ubnt EdgeRouter 里提过贵州电信的光纤网络对外就是这个地址段。 WireGuard的配置过程参考之前的文章，此处不多解释，只贴配置。 Incoming search terms:edgerouter wiregaurdwireguard vps部署DDDDDD===]D-==;PPPPP2]Q2]2]]]2]2]WireGuard 全球网centos7 wireguardwireguard 内网exercise2lcsm2185852slow4xdsad2zpPackage: 1:wireguard-dkms-0 0 20181018-1 el7 noarch (jdoss-wireguard) Requires: dkmsinvolvedji2furtherpgnfollowe5538IDyesg8yError: Package: 1:wireguard-dkms-0 0 20180910-1 el7 noarch (jdoss-wireguard) Requires: dkmsdifferent7dndepth9abdebian9 wireguardLink to this post!

EdgeRouter 部署 WireGuard

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

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

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

configure

set interfaces wireguard wg0 address 192.168.10.40/24

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

WireGuard wg-quick PostUp的高级玩法

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
