    栏目:win服务器问题汇总 时间:2019-11-01 10:36

    新建 一个bat文件,复制如下内容到bat文件中,将文件名命名为drop-udp.bat

    复制代码 代码如下:
    netsh ipsec static add policy name=dropudp
    netsh ipsec static add filterlist name=allow-udp
    netsh ipsec static add filterlist name=drop-udp

    REM 添加筛选器到IP筛选器列表(允许上网)
    netsh ipsec static add filter filterlist=allow-udp srcaddr=me dstaddr=any description=dns访问 protocol=udp mirrored=yesdstport=53
    netsh ipsec static add filter filterlist=allow-udp srcaddr=me dstaddr=any description=dns访问 protocol=udp mirrored=yesdstport=123
    netsh ipsec static add filter filterlist=allow-udp srcaddr=me dstaddr=any description=dns访问 protocol=udp mirrored=yesdstport=161

    REM 添加筛选器到IP筛选器列表(不让别人访问)
    netsh ipsec static add filter filterlist=drop-udp srcaddr=any dstaddr=me description=别人到我任何访问 protocol=udp mirrored=yes

    REM 添加筛选器操作
    netsh ipsec static add filteraction name=allow-udp-port action=permit
    netsh ipsec static add filteraction name=drop-udp-port action=block

    REM 创建一个链接指定 IPSec 策略、筛选器列表和筛选器操作的规则(加入规则到我的安全策略)
    netsh ipsec static add rule name=允许规则 policy=dropudp filterlist=allow-udp filteraction=allow-udp-port
    netsh ipsec static add rule name=拒绝规则 policy=dropudp filterlist=drop-udp filteraction=drop-udp-port

    REM 激活我的安全策略
    netsh ipsec static setpolicy name=dropudp assign=y
     

    保存后,双击运行即可
    udp除53 DNS解析,161 snmp监控端口 及时间同步服务123这三个udp的端口外,禁用所有udp出入站连接
