windows10添加tcp端口转发

1、添加端口转发

• 指定IP

netsh interface portproxy add v4tov4 listenport=4000 listenaddress=127.0.0.1 connectport=4000 connectaddress=172.31.217.198

• 不指定IP

netsh interface portproxy add v4tov4 listenport=4000 connectaddress=172.31.217.198 connectport=4000

2、删除端口转发

netsh interface portproxy del v4tov4 listenport=4000 listenaddress=127.0.0.1

3、查看已存在的端口映射

netsh interface portproxy show all
或
netsh interface portproxy show v4tov4

4.可以通过命令检查

netstat -ano|find 4000 查看端口是否已在监听
telnet 127.0.0.1 4000 测试端口是否连通
