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.

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

EdgeRouter 策略路由实现分析

By @sskaje
Link: https://sskaje.me/2017/06/edgerouter-policy-based-routing-analysis/

最近家里的路由规则越来越复杂，而且越来越好用。正好昨天跟朋友讨论他的家用路由改造方案，所以研究了一下EdgeRouter的策略路由（Policy-based Routing，PBR）的实现。

我家里的路由是EdgeRouter Lite，固件1.9.1.1，这个实现跟固件关系不大。

首先，我们可以参考一下官方的文档：EdgeRouter – Policy-based routing (source address based)

EdgeRouter + SoftEther Policy-based Routing Error

By @sskaje
Link: https://sskaje.me/2017/06/edgerouter-softether-policy-based-routing-error/

I have protocol config like

protocols {
  static {
    table 4 {
      route 0.0.0.0/0 {
        next-hop 192.168.10.1 {
        }
      }
    }
  }
}

protocols {

static {

table 4 {

route 0.0.0.0/0 {

next-hop 192.168.10.1 {

}

SoftEther TAP device name is tap_se, local ip is 192.168.10.2, remote ip 192.168.10.1.

Internet is connected via pppoe0.

Policy-based routing modified to table 4 route traffic to pppoe0 rather than tap_se.

Check current route table:

root@ubnt:/home/ubnt# show ip route table 4
default via 192.168.10.1 dev pppoe0

1 2	root@ubnt:/home/ubnt# show ip route table 4 default via 192.168.10.1 dev pppoe0

In my previous post, I added a softether start-up script in /config/scripts/post-config.d/.
I guess vpnserver is launched after policy-based routing rules been applied, that causes policy-based routing find no device/connected routes for 192.168.10.1, then pppoe0 is picked.

I don’t have any good idea (add custom config template is a good choice, but i’m lazy zzZZ..), just disable and re-enable that route table after router is booted.

configure
set protocols static table 4 route 0.0.0.0/0 next-hop 192.168.10.1 disable
commit
delete protocols static table 4 route 0.0.0.0/0 next-hop 192.168.10.1 disable
commit
