冲击波路由配置:

access-list 115 deny udp any any eq 69
access-list 115 deny tcp any any eq 135
access-list 115 deny udp any any eq 135
access-list 115 deny udp any any eq 137
access-list 115 deny udp any any eq 138
access-list 115 deny tcp any any eq 139
access-list 115 deny udp any any eq 139
access-list 115 deny tcp any any eq 445
access-list 115 deny tcp any any eq 593
access-list 115 deny tcp any any eq 4444
access-list 115 permit ip any any
interface <interface>
ip access-group 115 in
ip access-group 115 out

另外，阻止非法地址的命令是
Router(config)# interface <interface>
Router(if-config)# no ip unreachables
如果此命令不能禁止，可参考下面这个命令
Elab(config)# ip icmp rate-limit unreachable <millisecond
