This is just a reminder for me. So may not have so many details.

Dependency:

• opkg install iptables-mod-nat-extra
• Shadowsocks (libpolarssl is its dependency, install it from trunk and make symbol links).
• dnsmasq (it should be installed by default)

Steps:

Rules: Generate on your machine, move to your OpenWRT.

• Generate fuck_gfw.sh by gen_shadowsocks.sh, and move it to /usr/bin. chmod +x if necessary.
• Move fuckgfw_dns.conf to /etc/dnsmasq.d, and add conf-dir=/etc/dnsmasq.d to /etc/dnsmasq.conf.
• Cofing /etc/shadowsocks.json, the port should be the same defined in gen_shadowsocks.sh.
• Move the fuck_gfw to /etc/init.d, chmod +x if necessary.
• Start and enjoy it!
