H3C-ICG3000路由器如何配置LAN口网段下联用户高危端口(135、139、445等)封堵策略?

最佳答案
您好,可以使用高级ACL来关闭,以下是参考命令:
1、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

LAN网段IP是做在设备VLAN接口下,比如vlan 10,设备物理口是port access vlan 10 ,我这个情况如何下发配置?ACL已经创建好了,比如我的是acl nuber 3001
(0)
int range gi 1/0/1 packet-filter 3001 inbound packet-filter 3001 outbound
int range gi 1/0/1 gi 1/0/24 packet-filter 3210 inbound packet-filter 3210 outbound就是在物理接口下做
int range gi 1/0/1 packet-filter 3001 inbound packet-filter 3001 outbound
