Windows下实现端口转发

Windows下可以使用netsh做端口转发：

# 将192.168.5.3的22端口转发到xxx.xxx.xxx.xxx的22端口
netsh interface portproxy add v4tov4 listenaddress=192.168.5.3 listenport=22 connectaddress=xxx.xxx.xxx.xxx connectport=22
# 查看存在的转发
netsh interface portproxy show all
# 删除IP是192.168.5.3，端口是22的转发
netsh interface portproxy delete v4tov4 listenaddress=192.168.5.3 listenport=22
