windows进行端口映射

1. 查询端口映射情况

netsh interface portproxy show v4tov4

2. 查询某一个IP的所有端口映射情况

netsh interface portproxy show v4tov4 | find "[IP]"
# 例：
netsh interface portproxy show v4tov4 | find "192.168.1.1"

3. 增加一个端口映射

netsh interface portproxy add v4tov4 listenaddress=[外网IP] listenport=[外网端口] connectaddress=[内网IP] connectport=[内网端口]
# 例：
netsh interface portproxy add v4tov4 listenaddress=2.2.2.2 listenport=8080 connectaddress=192.168.1.50 connectport=80

4. 删除一个端口映射

netsh interface portproxy delete v4tov4 listenaddress=[外网IP] listenport=[外网端口]
# 例：
netsh interface portproxy delete v4tov4 listenaddress=2.2.2.2 listenport=8080
