搭配可以使用的软件
ChinaDNS 1.3.2-3
luci-app-chinadns 1.4.0-1
luci-app-shadowsocks 1.3.7-1
shadowsocks-libev 2.5.6-1

原来的源不行，要修改

升级出错可能是wget不支持ssl，更新可以http的源后，即可。

把本机，ip1.1.1.1，端口9002，转发到 2.2.2.2的8080

echo “1” > /proc/sys/net/ipv4/ip_forward
sysctl -p
iptables -t nat -A PREROUTING -d 1.1.1.1 -p tcp –dport 9002 -j DNAT –to-destination 2.2.2.2:8080
iptables -t nat -A POSTROUTING -d 2.2.2.2 -p tcp –dport 8080 -j SNAT –to-source 1.1.1.1
