This scheme is suitable for the Raspberry Pi hardware, do not want to make changes in the router friends, this is a network can be all over, but also according to the destination IP (domestic and non-domestic routing, not all data go ss), of course, if there is a better solution or error please point out.

Preparatory work:
1:raspberry B + (recommended A + +, this version of the relatively big progress in the other, specifically do not say their own Google), which is almost equivalent to a Linux computer in the LAN, and finally routed through it.
2: A certain familiarity with Linux, but if you are confident, Google can also.
3:banwagon, this doesn't explain.
4: Suppose you are already a root account.

Solution Ideas:
1: Resolve DNS pollution;
2: Packet walk shadowsocks;

The installation configuration of the Raspberry PI B + is as follows:
#升级一下现有的组件
Apt-get Update
Apt-get Install Dnsutils

#shadowsocks Installation:
Apt-get Install Libssl-dev
git clone https://github.com/shadowsocks/shadowsocks-libev.git
CD Shadowsocks-libev
./configure
Make
Make install

#shadowsocks configuration, where server_ip and Port are VPS (bandwagon) already set (server side configuration is not a problem)
Vi/etc/shadowsocks_vps.json
{
"Server": "Server_ip",
"Server_port": Server_port,
"Local_address": "0.0.0.0",
"Local_port": 1080,
"Password": "Password",
"Timeout": 3000,
"Method": "AES-256-CFB",
"Workers": 10
}


#下载安装ChinaDNS
Https://github.com/clowwindy/ChinaDNS-C/releases/download/1.2.1/chinadns-c-1.2.1.tar.gz
TAR-ZXF chinadns-c-1.2.1.tar.gz
CD chinadns-c-1.2.1
./configure
Make
Make install


#下载安装redsocks
Apt-get Install Redsocks
#修改配置:
Vi/etc/redsocks.conf
Log_info = off;
To modify the Redsocks segment:
Local IP 127.0.0.1 = 0.0.0.0
Local_port to 1081 (redsocks port)
Port is SOCKS5 (port)

#开机启动, including the setting of the Iptabls:
Vi/etc/rc.local
Nohup/usr/local/bin/ss-local-c/etc/shadowsocks_vps.json-u--acl/root/shadowsocks-libev/acl/chn.acl >/dev/null &
Nohup/usr/sbin/redsocks-c/etc/redsocks.conf >/dev/null &
Nohup/usr/local/bin/ss-tunnel-c/etc/shadowsocks_vps.json-l 5353-l 8.8.4.4:53-u >/dev/null &
Nohup/root/chinadns-c-1.2.1/src/chinadns-s "114.114.114.114,127.0.0.1:5353"-l/root/chinadns-c-1.2.1/iplist.txt- C/root/chinadns-c-1.2.1/chnroute.txt >/dev/null &

Iptables-t nat-f
Iptables-t Nat-n Redsocks
Iptables-t Nat-n Redsocks_filter

#本地和保留地址放行, the others go to the last rule (forward to port 1081)
Iptables-t nat-a redsocks_filter-d 0.0.0.0/8-j RETURN
Iptables-t nat-a redsocks_filter-d 127.0.0.0/8-j RETURN
Iptables-t nat-a redsocks_filter-d 192.168.1.0/24-j RETURN
Iptables-t nat-a redsocks_filter-d 192.168.0.0/24-j RETURN
Iptables-t nat-a redsocks_filter-j Redsocks

#转发到1081端口
Iptables-t nat-a redsocks-p tcp-j REDIRECT--to-port 1081

#进来的数据包进入指定的chains (top)
Iptables-t nat-a prerouting-p tcp-j redsocks_filter


Below is the configuration of the bandwagon:
1: Install the Debian system, you should install the latest.
2:apt-get Install git Libssl-dev
3:shadowsocks installation: (as above, as this already includes services and clients)
#修改配置, Port is the server port configured for the upper Raspberry Pi B + configuration, same as the password.
/etc/shadowsocks_vps.json
{
"Server": "0.0.0.0",
"Server_port":p ort,
"Local_port": 1881,
"Password": "Password",
"Method": "AES-256-CFB",
"Timeout": 3000
}

#执行, note: To add the-u parameter
4: Executive Nohup/usr/local/bin/ss-server-u-c/etc/shadowsocks_vps.json >/dev/null &



#最后修改路由器的默认网关和DNS为这个raspberry the Pi B + IP
