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。

配置

基本知识

默认账号密码为ubnt/ubnt，可以使用web（https）或SSH连接。本次配置以命令行为主，可以选择使用Web的Console或者SSH。

1 PPTP客户端

官方有文档，http://wiki.ubnt.com/PPTP_Client_-_CLI_Commands。
server-ip可以支持域名或者IP。

configure
edit interfaces pptp-client pptpc0
set user-id sskaje
set password sskaje
set server-ip sskaje.me
set require-mppe
commit
save
exit

connect interface pptpc0

configure

edit interfaces pptp-client pptpc0

set user-id sskaje

set password sskaje

set server-ip sskaje.me

set require-mppe

commit

save

exit

connect interface pptpc0

这些没什么可解释的。

2 确定目标网络IP段

Google

Google的IP段之前搞过一次，Google IP Address Ranges。spf纪录，点开文章看就行。

Twitter

Twitter的一样.

Facebook

Facebook的spf记录没什么用，但是官方给了个获取IP的方法：Sharing Best Practices for Websites & Mobile Apps

whois -h whois.radb.net -- '-i origin AS32934' | grep ^route

1	whois -h whois.radb.net -- '-i origin AS32934' \| grep ^route

这个表里有重复的，需要去重。

完成上述操作后，可能会整理出一个很多行的网段列表，而去很多网段可以合并。这里推荐自己写的网段合并的PHP类：https://github.com/sskaje/ip_calc.
整理之后，我人肉把所有的网络都合并成了 CIDR 16。

3 配置Firewall Network Group

~~配置Network Group的目的是给NAT用。~~
没什么用

4 NAT

这块我是从web端点的，没有去看命令怎么配。贴一段配置文件：

    nat {
        rule 5000 {
            description "masq to pptp"
            log disable
            outbound-interface pptpc0
            protocol all
            type masquerade
        }
        rule 5001 {
            description default
            log disable
            outbound-interface eth1
            protocol all
            type masquerade
        }
    }

nat {

rule 5000 {

description "masq to pptp"

log disable

outbound-interface pptpc0

protocol all

type masquerade

}

rule 5001 {

description default

log disable

outbound-interface eth1

protocol all

type masquerade

}

5 静态路由

人肉点或者命令行用如下参数：

set protocols static interface-route 10.1.1.0/24 next-hop-interface pptpc0

1	set protocols static interface-route 10.1.1.0/24 next-hop-interface pptpc0

自己替换一下上边的网络列表

6 DNS

DNS污染是墙的基本功能。
系统自带的DNS服务基于Dnsmasq, 文档在 http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html
按照如下参数配置所有需要使用vpn解析的域名记录。

set service dns forwarding options server=/google.com/8.8.8.8

1	set service dns forwarding options server=/google.com/8.8.8.8
