防火墙管理
恢复初始防火墙设置
netsh advfirewall reset关闭/开启防火墙
netsh advfirewall set allprofiles state off/on查看防火墙策略
netsh advfirewall firewall show rule name=all设置默认出入策略：允许/禁止
netsh advfirewall set allprofiles firewallpolicy allowinbound/blockinbound,allowoutbound/blockoutbound端口管理
开启/关闭端口TCP/UDP
netsh advfirewall firewall add rule name="说明或备注" dir=in protocol=tcp/udp localport=端口 action=allow/block端口转发
显示端口转发
netsh interface portproxy show all开启端口转发
netsh interface portproxy add v4tov4 listenaddress=192.168.10.2 listenport=120 connectaddress=192.168.10.3 connectport=22删除端口转发
netsh interface portproxy delete v4tov4 listenaddress=192.168.10.2 listenport=120网卡管理
查看网卡接口
netsh interface show interface禁用/启用网卡
netsh interface set interface "接口名称" disabled/enabled修改IP地址addr和子网掩码mask
netsh interface ip set address name="接口名称" source=static addr=192.168.10.100 mask=255.255.255.0修改网关gateway
netsh interface ip set address name="接口名称" gateway=192.168.10.1 gwmetric=0修改首选(PRIMARY)的DNS
netsh interface ip set dns name="接口名称" source=static addr=8.8.8.8 register=PRIMARY复合命令：判断端口是否监听
netstat -ano -p tcp | findstr "443" >nul 2>nul && echo 端口状态：已监听 || echo 端口状态：未监听参考
