EdgeRouter PPtP Server访问本地DNS服务

UBNT EdgeRouter 自带了PPTP Server，典型的配置方法是

set vpn pptp remote-access authentication local-users username sskaje password PASSWORD
set vpn pptp remote-access authentication mode local
set vpn pptp remote-access client-ip-pool start 192.168.100.210
set vpn pptp remote-access client-ip-pool stop 192.168.100.219
set vpn pptp remote-access dns-servers server-1 8.8.8.8
set vpn pptp remote-access mtu 1492

set vpn pptp remote-access authentication local-users username sskaje password PASSWORD

set vpn pptp remote-access authentication mode local

set vpn pptp remote-access client-ip-pool start 192.168.100.210

set vpn pptp remote-access client-ip-pool stop 192.168.100.219

set vpn pptp remote-access dns-servers server-1 8.8.8.8

set vpn pptp remote-access mtu 1492

官方参考guide: https://help.ubnt.com/hc/en-us/articles/205220840-EdgeMAX-PPTP-VPN-with-local-users-RADIUS 这个案例里，我的路由eth0是LAN口，eth0的IP是 192.168.100.1，这个配置下我的pptp客户端能正常访问到我的内网的机器。但是如果我需要把DNS设成 192.168.100.1，DNS请求就会一直没响应。路由端抓 UDP 53 的包，可以看到pptp客户端发出的dns请求，但是没有回包。看了眼/etc/dnsmasq.conf:

log-facility=/var/log/dnsmasq.log
interface=eth0
interface=eth2
cache-size=10000

log-facility=/var/log/dnsmasq.log

interface=eth0

interface=eth2

cache-size=10000

man dnsmasq -i, –interface= Listen only on the specified interface(s). Dnsmasq automatically adds the loopback (local) interface to the list of interfaces to use when the –interface option is used. If no –interface or –listen-address options are given … Continue reading “EdgeRouter PPtP Server访问本地DNS服务”

UBNT VPN + Socks5 代理

VPN的方案可以参考 Set up OpenVPN Site-to-Site on UBNT EdgeRouter Lite 或 EdgeOS PPTP VPN客户端配置。由于某些国际CDN的问题，部分网站不适合用IP路由来设定跳转。所以这里的需求是，针对特定域名把80/443的请求转由VPN的设备出去，其他的不管。思路1，用EdgeMax自带的webproxy功能，但是很可惜，squid不支持选择outgoing的interface，只能选目标IP。所以放弃。思路2，DPI监测域名或SNI，但是EdgeRouter Lite的最新版beta 1.8.0b3文档不完整，自己测试了一下相关命令，没搞成，理论上有戏。思路3，本地socks5代理。我一直会用firefox+foxyproxy作为专用浏览器，正常的需求都用chrome。而且最近secure pipes经常掉，不确定什么情况，包括用国内vps代理远端ssh的方案也不行。尝试了一些方案，包括dante-server 选上行interface, SSH Tunnel + DNAT，都不行。DNAT的方案不想直接用iptables，怕配置命令保存不方便，所以最终回到了haproxy的方案。 VPS上，配置socks5代理。方案很简单，参考命令如下：

ssh -f -N -D 10.99.99.2:31080 -D 192.168.121.1:31080 sskaje@127.0.0.1

1	ssh -f -N -D 10.99.99.2:31080 -D 192.168.121.1:31080 sskaje@127.0.0.1

10.99.99.2 和 192.168.121.1 分别是我两种vpn方案的服务端私有IP。这行命令被我加到了rc.local。当然，还得配ssh 公钥登录。路由上，安装配置haproxy。依旧参考使用HAProxy搭建SSH代理。 /etc/haproxy/haproxy.cfg

TunnelBroker for EdgeRouter Lite

创建隧道在北京联通这种不给IPv6网络的ISP下生存，总有走v6翻墙的欲望。免费的Tunnel服务很多，最出名莫过HE.net的TunnelBroker 首先申请一个Tunnel。访问：

https://tunnelbroker.net/new_tunnel.php

1	https://tunnelbroker.net/new_tunnel.php

注册登录之后，创建并输入当前路由公网IP “YOUR.ROUTER.INTERNET.IP”。创建成功后会被跳转到

https://tunnelbroker.net/tunnel_detail.php?tid=XXXXX

1	https://tunnelbroker.net/tunnel_detail.php?tid=XXXXX

XXXXX的部分是一串数字，所谓的Tunnel ID. 在这个页面上选择第二个标签页 “Example Configurations” 选择 “Vyatta / Ubiquiti EdgeMAX” 文本框会自动生成如下配置：

configure
edit interfaces tunnel tun0
set encapsulation sit
set local-ip YOUR.ROUTER.INTERNET.IP
set remote-ip 74.82.46.6
set address 2001:470:23:XXXX::XX/64
set description "HE.NET IPv6 Tunnel"
exit
set protocols static interface-route6 ::/0 next-hop-interface tun0
commit

configure

edit interfaces tunnel tun0

set encapsulation sit

set local-ip YOUR.ROUTER.INTERNET.IP

set remote-ip 74.82.46.6

set address 2001:470:23:XXXX::XX/64

set description "HE.NET IPv6 Tunnel"

exit

set protocols static interface-route6 ::/0 next-hop-interface tun0

commit

remote-ip是创建时选择的远端服务器IP，local-ip是本地当前的出口IP。鉴于ISP给的IP都是动态的，所以local-ip改成如下‘0.0.0.0’。如果之前有配置过tunnel，需要重新配置，则先删除既有的：

delete interfaces tunnel tun0

1	delete interfaces tunnel tun0

下面开始命令配置tunnel

configure
# tun to ipv6
edit interfaces tunnel tun0
set encapsulation sit
set local-ip 0.0.0.0
set remote-ip 74.82.46.6
set address 2001:470:23:XXXX::XX/64
set description "HE.NET IPv6 Tunnel"
exit
set protocols static interface-route6 ::/0 next-hop-interface tun0
