方式一：通过防火墙

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/本地任意IP] listenport=[外网端口] connectaddress=[内网/远程IP] connectport=[内网端口]

例：
listenaddress=0.0.0.0 为本地IP，四个零代表本地任意IP
listenport=443 本地端口
connectaddress=43.156.232.70 需要转发的远程IP
connectport=443 远程IP

netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=443 connectaddress=43.156.232.70 connectport=443

使用netsh命令在Windows上将222端口转发到3333端口：
netsh interface portproxy add v4tov4 listenaddress=本机IP地址 listenport=222 connectaddress=本机IP地址 connectport=3333

netsh interface portproxy add v4tov4 listenaddress=172.19.166.10 listenport=53389 connectaddress=172.19.166.10 connectport=3389

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=0.0.0.0 listenport=443

实验：将部署在内网的服务映射到外网

实验环境

  1. VMWare Workstation Pro
  2. 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
Ethernet0192.168.50.105255.255.255.0-内网网卡
Ethernet1172.16.2.105255.255.255.0-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


方式二：路由和远程访问

注意：仅支持内网服务器的端口映射
