创建ACL,对高危端口进行拦截:
acl number 3210
rule 0 deny tcp destination-port eq 135
rule 1 deny udp destination-port eq 135
rule 2 deny tcp destination-port eq 137
rule 3 deny udp destination-port eq netbios-ns
rule 4 deny tcp destination-port eq 138
rule 5 deny udp destination-port eq netbios-dgm
rule 6 deny udp destination-port eq netbios-ssn
rule 7 deny tcp destination-port eq 139
rule 8 deny tcp destination-port eq 445
rule 9 deny udp destination-port eq 445
rule 10 deny tcp destination-port eq 3389
rule 11 deny udp destination-port eq 3389
rule 20 deny tcp source-port eq 135
rule 21 deny udp source-port eq 135
rule 22 deny tcp source-port eq 137
rule 23 deny udp source-port eq netbios-ns
rule 24 deny tcp source-port eq 138
rule 25 deny udp source-port eq netbios-dgm
rule 26 deny udp source-port eq netbios-ssn
rule 27 deny tcp source-port eq 139
rule 28 deny tcp source-port eq 445
rule 29 deny udp source-port eq 445
rule 30 deny tcp source-port eq 3389
rule 31 deny udp source-port eq 3389
rule 1500 permit ip
2、将ACL下发到端口:
int range gi 1/0/1 gi 1/0/24
packet-filter 3210 inbound
packet-filter 3210 outbound
quit
