1、查询端口映射情况netsh interface portproxy show v4tov4查询这个IP所有的端口映射。
2、查询物理机网卡的信息，确定能上网的网卡参数
3、增加一个端口映射netsh interface portpro垓矗梅吒xy add v4tov4 listenport=外网端口 listenaddress=主IP connectaddress=私网IP connectport=私网IP端口增加一个端口映射netsh interface portproxy add v4tov4 listenport=外网端口 listenaddress=主IP connectaddress=私网IP connectport=私网IP端口例如：netsh interface portproxy add v4tov4 listenport=8888 listenaddress=118.123.13.180 connectaddress=192.168.1.10 connectport=2222
4、设置好之后，查询一下端口映射是否正常。
5、内网端口可以不一致netsh interface portproxy add v4tov4 listenport=2022 listenaddress=119.1桃轾庾殇46.62.231 connectaddress=192.168.1.251 connectport=22
6、删除映射netsh interface portproxy delete v4tov4 listenaddress=119.146.62.231 listenport=2022
