socat 转发 和 nginx 包转发

centos上转发

yum install -y socat

ubuntu

apt-get update apt-get install -y socat

socat的使用

1、转发TCP nohup socat TCP4-LISTEN:30000,reuseaddr,fork TCP4:1.1.1.1:30000 >> socat.log 2>&1 & 2、转发UDP nohup socat -T 600 UDP4-LISTEN:10000,reuseaddr,fork UDP4:1.1.1.1:10000 >> socat.log 2>&1 &

nginx tcp转发

user nobody;
worker_processes auto;
 
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
 
#pid logs/nginx.pid;
 
 
events {
use epoll;
worker_connections 1024;
}
 
 
stream {
　　server {
　　listen 3000;
　　proxy_pass 127.0.0.1:3306;
 
　　4# 也支持socket
　　4# proxy_pass unix:/var/lib/mysql/mysql.socket;
　　}
}

nginx udp 转发

user nobody;
worker_processes auto;
 
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
 
#pid logs/nginx.pid;
 
 
events {
use epoll;
worker_connections 1024;
}
 
 
stream {
　　server {
　　listen 3000 udp;
　　proxy_pass 127.0.0.1:3001;
 }
}

windows 工具转发

netsh interface portproxy add v4tov4 listenaddress=172.16.0.4 listenport=8080 connectaddress=104.104.104.104 connectport=9999
