_netblocks3.google.com is currently empty. Now we have list of IPv4 ranges, but we know google provides a public dns service, 8.8.8.8/8.8.4.4 (for ipv6 2001:4860:4860::8888/2001:4860:4860::8844). we can treat these two as … Continue reading “Google IP Address Ranges”

OpenConnect DNS Only + Google Only

I’m using 4G by China Mobile, but the DNS it provides really sucks. Changing DNS from Cellular Data on a not-jailbroken iPhone is impossible so far as I know (I tried mobileconfig but can find any working options). The first idea is pushing DNS from a PPTP server, which I wrote: Notes: PPTP/L2TP Server on … Continue reading “OpenConnect DNS Only + Google Only”

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
commit
save

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

Router Advert 配置完tunnel，就得配局域网内的配置了，毕竟只有路由能上v6是不够的

        }                         
        speed auto

如果你本地的DNS规则有过配置，radvd-options 的配置一定要把ipv6地址设成路由器的v6地址实践证明，我之前折腾了好久的dhcpv6没用，但是配置也可以贴出来

自动更新IP 之前一片EdgeRouter Lite相关的配置文章里，我把He.net提供的DDNS配置好了。Dynamic DNS on HE.net, HE.net Dynamic DNS on Ubiquiti Router. 脚本更新首先按如下路径生成ddns专用的key

TunnelBroker.net -> Tunnel Details -> Advanced -> Update Key

1	TunnelBroker.net -> Tunnel Details -> Advanced -> Update Key

尝试过好多次，EdgeRouter Lite无法通过配置参数添加多个同类型的ddns配置。所以先提供一个简单粗暴的方法。参考 https://forums.he.net/index.php?topic=1994.0 的说明，有如下的客户端语法： … Continue reading “TunnelBroker for EdgeRouter Lite”

EdgeOS PPTP VPN客户端配置

背景及目标买了个Ubnt EdgeRouter Lite，应同事的需求，研究配置自动翻墙。考虑过之前配置的各种VPN：PPTP、L2TP、IPSec、AnyConnect/OpenConnect。目前搞定的只有PPTP。本次配置使用远程PPTP Server，只考虑Google、Twitter和Facebook的自动翻墙，其他可以参照思路自己加路由和NAT。环境假设网络已经配置好，eth0为内网口，eth1为外网口。 Incoming search terms:edgemax pptp firewalledgeos ipsecedgerouter pptplinux墙翻自动ubnt 翻墙翻墙自动翻墙Link to this post!
