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
实验：将部署在内网的服务映射到外网
实验环境
- VMWare Workstation Pro
- 5台最小化安装的Windows虚拟机
如果Server4为Windows，替换一下相应的命令即可
Windows的IP信息如下
| 网卡 | IP地址 | 子网掩码 | 默认网关 | 备注 |
|---|---|---|---|---|
| Ethernet0 | 192.168.50.105 | 255.255.255.0 | - | 内网网卡 |
| Ethernet1 | 172.16.2.105 | 255.255.255.0 | - | 外网网卡 |
配置并查看端口映射情况
netsh interface portproxy add v4tov4 listenaddress=172.16.2.105 listenport=8081 connectaddress=192.168.50.11 connectport=8080
netsh interface portproxy add v4tov4 listenaddress=172.16.2.105 listenport=8082 connectaddress=192.168.50.12 connectport=8080
netsh interface portproxy show v4tov4
检查效果
在client节点上
curl http://172.16.2.105:8081/index.html
curl http://172.16.2.105:8082/index.html
curl http://172.16.2.11:8080/index.html
