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:asus merlinmerlin openvpn policy basedunderkdfasus ac88 site to site openvpnopenvpn pbr iptables tagsofficesn8nosev67nervous8xdleft1i1golden2w5gettingpohdryu82Create NAT on tunnelcountryljycopyozjcontinued8x6boxz65been1nnasus openvpnasus open vpn … Continue reading “OpenVPN Site-to-Site VPN between Asus Merlin And Ubnt EdgeRouter”

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:bright5smedgerouter iptables forwardedgerouter max-4 cpu架构vyos mipsLink to this post!

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 … Continue reading “EdgeRouter + SoftEther Policy-based Routing Error”

EdgeRouter Policy Based Routing Using DNSMASQ IPSET

之前用SNIProxy按域名区分流量，着实麻烦。尤其是后期发现路由表莫名其妙出问题。 EdgeRouter的Policy Based Routing(PBR)使用的是自带配置语法的firewall modify功能。官方有两篇教程： EdgeRouter – Policy-based routing for destination port EdgeRouter – Policy-based routing (source address based) 第二篇文章顺带提了network-group。之前在配置VPN时，使用过network-group，还比较过使用firewall modify + network-group 与配置一堆interface-route的区别。而，这里的network-group的实现，使用了netfilter的ipset。Man pages可以看这里，命令在edgerouter上也附带了。 dnsmasq支持 ‘–ipset‘ 参数，把对配置域名解析的IP存入到指定的ipset。具体细节可以看dnsmasq的文档。 dnsmasq配置的语法比较简单。

--ipset=/<domain>/[domain/]<ipset>[,<ipset>]

1	--ipset=/<domain>/[domain/]<ipset>[,<ipset>]

domain 部分参考 address 的语法。例如：

ipset=/.sskaje.me/MY_SET
ipset=/test.com/MY_SET

1 2	ipset=/.sskaje.me/MY_SET ipset=/test.com/MY_SET

配置好所有自己需要的域名，重启dnsmasq即可。 ipset本身支持timeout，但是edge os的network-group不支持，所以在配置dnsmasq之前，最好创建一个新的network-group。假定新建的ipset名叫 MY_SET，edge router的主要相关配置如下：

set firewall group network-group MY_SET

set firewall modify AUTO_VPN rule 20 action modify
set firewall modify AUTO_VPN rule 20 destination group network-group MY_SET
set firewall modify AUTO_VPN rule 20 modify table 4
set firewall modify AUTO_VPN rule 20 protocol all

set firewall group network-group MY_SET

set firewall modify AUTO_VPN rule 20 action modify

set firewall modify AUTO_VPN rule 20 destination group network-group MY_SET

set firewall modify AUTO_VPN rule 20 modify table 4

set firewall modify AUTO_VPN rule 20 protocol all

其他诸如配置 static table, interface firewall 可以参考最前边的文档。 Incoming search terms:edgeos firewall network-group … Continue reading “EdgeRouter Policy Based Routing Using DNSMASQ IPSET”
