刚用 nmap 扫了一下常用的 1000 个 UDP 端口的结果
localhost:~# nmap -sU **.**.**.**
Not shown: 987 closed ports
PORT STATE SERVICE
53/udp open|filtered domain
67/udp open|filtered dhcps
69/udp open|filtered tftp
135/udp open|filtered msrpc
137/udp open|filtered netbios-ns
138/udp open|filtered netbios-dgm
139/udp open|filtered netbios-ssn
445/udp open|filtered microsoft-ds
500/udp open isakmp
593/udp open|filtered http-rpc-epmap
1434/udp open|filtered ms-sql-m
1900/udp open|filtered upnp
4500/udp open|filtered nat-t-ike
有没有懂得大佬分析下,我刚试了下 53 端口是 DNS 服务,可以对 WAN 口提供 DNS 服务,可是我并没有转发这个端口~
