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 vpnauthor6hzclose13rfutureh1cherq81leadp9hopenvpn site to site配置satxfostripjqgLink to this post!

Ubnt EdgeRouter Lite 和 EdgeRouter X 上安装使用SNIProxy

EdgerRouter Lite和EdgerRouter X使用的固件版本 1.9.0 是基于debian wheezy的，但是debian wheezy现在已经进入LTS了，mips和mipsel不在官方的维护架构里，以至于现在无法使用官方的apt更新debian-security，而且在ubnt的路由上，安装很多开发库都没法搞了。 EdgerRoute Lite 使用的是mips64，debian源里需要用 mips 的包；而 EdgeRoute X 使用的是mipsel。使用lscpu看CPU的信息： EdgeRouter Lite

配置请参考官方文档。按我的需求，官方的功能没法满足，所以我对官方的源码做了一些改动，具体可见 https://github.com/sskaje/sniproxy。使用首先修改 /etc/default/sniproxy，这样才可以使用init的脚本启动

# Defaults for sniproxy initscript

# This file has two functions:
# 1) to completely disable starting sniproxy,
# 2) to select an alternative config file
#    by setting DAEMON_ARGS to -c <file>

# Additional options that are passed to the Daemon.
DAEMON_ARGS="-c /etc/sniproxy.conf"

# Whether or not to run the sniproxy daemon; set to 0 to disable, 1 to enable.
ENABLED=1
