Set up OpenVPN Site-to-Site on UBNT EdgeRouter Lite

参考：https://help.ubnt.com/hc/en-us/articles/204949694-EdgeMAX-OpenVPN-Site-to-Site 不同的是，我一端是Ubuntu Linux，另一端是EdgeRouter Lite。实现的目的也是让EdgeRouter连上远程vpn实现XXXX。 PPTP的方案参考：EdgeOS PPTP VPN客户端配置环境 Ubuntu Linux, 10.99.99.2 EdgeRouter Lite, 10.99.99.1 配置EdgeRouter Lite SSH到Ubnt EdgeRouter Lite 生成共享密钥文件

generate vpn openvpn-key /config/auth/secret

1	generate vpn openvpn-key /config/auth/secret

OpenVPN Site-to-Site VPN between Asus Merlin And Ubnt EdgeRouter

前言 Network Topology RT-AC68U 使用PPPoE拨号上网，但是分配的IP是100.64.204.111, 看着像公网IP实际却是Carrier-grade NAT. 现在需要将RT-AC68U与一台在公网的EdgeRouter使用OpenVPN Site-to-Site连接起来，并在RT-AC68U端实现policy-based routing。需要让RT-AC68U下的所有设备能访问EdgeRouter LAN的网络，并根据需求透过VPS访问指定互联网。本实验参考下列文章： Set up OpenVPN Site-to-Site on UBNT EdgeRouter Lite EdgeRouter OpenVPN Connectivity Monitor EdgeRouter 策略路由实现分析 EdgeRouter Policy Based Routing Using DNSMASQ IPSET Incoming search terms:asuswrt-merlin site to site vpnauthor6hzfutureh1cherq81leadp9hsatxfostripjqgLink to this post!

EdgeRouter 策略路由实现分析

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) Incoming search terms:edgemax 策略路由Link to this post!

EdgeRouter OpenVPN Connectivity Monitor

VPN protocols are censored and blocked in China. I’ve set up an PPTP client and a Site-to-site OpenVPN connection on my EdgeRouter Lite. PPTP is insecure and is easier to censor, so I’ve removed PPTP client from my router. OpenVPN is better than PPTP, not only secured, but also much more stable. But traffics are … Continue reading “EdgeRouter OpenVPN Connectivity Monitor”

SNIProxy 绑定设备后连接超时

edgerouter lite 我之前是tun模式的openvpn site-to-site，网络拓扑很简单，local tun remote tun，简单配个ip就行，edgerouter上直接使用interface-route 跳转到local tun就行了。后来换用了softether，tap模式，于是需要自己配置IP和路由表。我简单地把firewall modify的地址组切到新的设备上，但是之前的 google dns 和 sniproxy 都保留在openvpn侧。但是最近openvpn被查的厉害，ssh也是被盯上了，所以不得不切换设备到 softether 的 tap 上。

listen 192.168.12.2:3543 {
    proto tls
    table https_hosts
    device tap_vbr
}

listen 192.168.12.2:3543 {

proto tls

table https_hosts

device tap_vbr

}

测试，发现连接超时。测试使用的域名是 download.oracle.com，解析的ip是 106.187.61.57。路由上tcpdump

tcpdump -n -i tap_vbr

1	tcpdump -n -i tap_vbr

看到的请求却是：

14:22:04.471223 ARP, Request who-has 106.187.61.57 tell 192.168.99.50, length 28

所以。。。加路由吧。因为公司是固定IP，所以之前配的是 system gateway-address。这个时候直接配静态路由会报错：

root@ubnt# set protocols static route 0.0.0.0/0 next-hop 192.168.99.1 distance 100
Error: can not combine system gateway and static default route

1 2	root@ubnt# set protocols static route 0.0.0.0/0 next-hop 192.168.99.1 distance 100 Error: can not combine system gateway and static default route

先删后加

root@ubnt# delete system gateway-address

root@ubnt# commit

注意一下，delete执行完后需要先commit，否则还会报错。验证一下

root@ubnt# netstat -nr

如果执行命令前会纠结是否生效，简单 route add 测试一下即可。无比保证vpn的metric比默认网关的大。另，interface-route + route 的混合模式没测试。 Incoming search terms:sniproxy ip rangeLink to this post!
