transparent TCP to SOCKS5 redirector

yellowsocks

yellowsocks类似于redsocks，是依赖iptables把tcp转换为socks5的全局代理工具。

配置代理

在linux或者路由器上启动，指定监听端口、socks5的地址端口。

./yellowsocks -l :4455 -t 127.0.0.1:1080

配置iptables

*nat

:PREROUTING ACCEPT [0:0]

:INPUT ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

:POSTROUTING ACCEPT [0:0]

:REDSOCKS - [0:0]

# Redirect all output through redsocks

-A OUTPUT -p tcp -j REDSOCKS

# Whitelist LANs and some other reserved addresses.

# https://en.wikipedia.org/wiki/Reserved_IP_addresses#Reserved_IPv4_addresses

-A REDSOCKS -d 0.0.0.0/8 -j RETURN

-A REDSOCKS -d 10.0.0.0/8 -j RETURN

-A REDSOCKS -d 127.0.0.0/8 -j RETURN

-A REDSOCKS -d 169.254.0.0/16 -j RETURN

-A REDSOCKS -d 172.16.0.0/12 -j RETURN

-A REDSOCKS -d 192.168.0.0/16 -j RETURN

-A REDSOCKS -d 224.0.0.0/4 -j RETURN

-A REDSOCKS -d 240.0.0.0/4 -j RETURN

-A REDSOCKS -d {socks5的ip地址} -j RETURN

-A REDSOCKS -p tcp --dport {socks5的端口} -j RETURN

# Redirect everything else to redsocks port

-A REDSOCKS -p tcp -j REDIRECT --to-ports 4455

openwrt配置

• 编译yellowsocks成路由器对应版本，如GOOS=linux GOARCH=mipsle go build
• 部分CPU需要在kernel里打开FPU，重新编译openwrt固件，编译方法参考官网
• 路由器启动后，在/etc/firewall.user添加转发规则

iptables -t nat -N YELLOWSOCKS
iptables -t nat -A PREROUTING -i br-lan -p tcp -j YELLOWSOCKS

# Do not redirect traffic to the followign address ranges
iptables -t nat -A YELLOWSOCKS -d 0.0.0.0/8 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 10.0.0.0/8 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 127.0.0.0/8 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 169.254.0.0/16 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 172.16.0.0/16 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 192.168.0.0/16 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 224.0.0.0/4 -j RETURN
iptables -t nat -A YELLOWSOCKS -d 240.0.0.0/4 -j RETURN

# Redirect all kinds of traffic
iptables -t nat -A YELLOWSOCKS -p tcp -j REDIRECT --to-ports 4455

• 启动yellowsocks

./yellowsocks -l :4455 -t sock5的ip:sock5的端口 -nolog 1 -noprint 1

• 如果上不去网，说明有dns污染，可以通过pingtunnel解决
• 设置openwrt自带的dnsmasq转发

uci add_list dhcp.@dnsmasq[0].server="127.0.0.1#5353"
uci set dhcp.@dnsmasq[0].noresolv="1"
uci set dhcp.@dnsmasq[0].localuse="1"
uci commit dhcp
/etc/init.d/dnsmasq restart

• 启动pingtunnel，转发dns到远端

./pingtunnel -type client -l :5353 -s yourserver -t 8.8.8.8:53 -key yourkey -nolog 1 -noprint 1

• 或者参考yellowdns
