使用ACL防病毒

使用ACL防病毒
建议：在配置病毒列表之前
1．
确认用户的业务端口与列表的规则不冲突。
2．
确认交换机或者路由器的性能可以承受访问控制列表的过滤。

创建acl
acl number 100
禁ping
rule deny icmp source any destination any
用于控制Blaster蠕虫的传播
rule deny udp source any destination any destination-port eq 69
rule deny tcp source any destination any destination-port eq 4444
用于控制冲击波病毒的扫描和攻击
rule deny tcp source any destination any destination-port eq 135
rule deny udp source any destination any destination-port eq 135
rule deny udp source any destination any destination-port eq netbios-ns
rule deny udp source any destination any destination-port eq netbios-dgm
rule deny tcp source any destination any destination-port eq 139
rule deny udp source any destination any destination-port eq 139
rule deny tcp source any destination any destination-port eq 445
rule deny udp source any destination any destination-port eq 445
rule deny udp source any destination any destination-port eq 593
rule deny tcp source any destination any destination-port eq 593
用于控制振荡波的扫描和攻击
rule deny tcp source any destination any destination-port eq 445
rule deny tcp source any destination any destination-port eq 5554
rule deny tcp source any destination any destination-port eq 9995
rule deny tcp source any destination any destination-port eq 9996
用于控制 Worm_MSBlast.A 蠕虫的传播
rule deny udp source any destination any destination-port eq 1434
下面的不出名的病毒端口号
（可以不作）
rule deny tcp source any destination any destination-port eq 1068
rule deny tcp source any destination any destination-port eq 5800
rule deny tcp source any destination any destination-port eq 5900
rule deny tcp source any destination any destination-port eq 10080
rule deny tcp source any destination any destination-port eq 455
rule deny udp source any destination any destination-port eq 455
rule deny tcp source any destination any destination-port eq 3208
rule deny tcp source any destination any destination-port eq 1871
rule deny tcp source any destination any destination-port eq 4510
rule deny udp source any destination any destination-port eq 4334
rule deny tcp source any destination any destination-port eq 4331
rule deny tcp source any destination any destination-port eq 4557
然后下发配置
packet-filter ip-group 100
目的：针对目前网上出现的问题，对目的是端口号为1434的UDP报文进行过滤的配置方法，详细和复杂的配置请看配置手册。

NE80的配置：
NE80(config)#rule-map r1 udp any any eq 1434
//r1为role-map的名字，udp 为关键字，any any 所有源、目的IP，eq为等于，1434为udp端口号
NE80(config)#acl a1 r1 deny
//a1为acl的名字，r1为要绑定的rule-map的名字，
NE80(config-if-Ethernet1/0/0)#access-group acl a1
//在1/0/0接口上绑定acl，acl为关键字，a1为acl的名字
NE16的配置：
NE16-4(config)#firewall enable all
//首先启动防火墙
NE16-4(config)#access-list 101 deny udp any any eq 1434
//deny为禁止的关键字，针对udp报文，any any 为所有源、目的IP，eq为等于， 1434为udp端口号
NE16-4(config-if-Ethernet2/2/0)#ip access-group 101 in
//在接口上启用access-list，in表示进来的报文，也可以用out表示出去的报文
中低端路由器的配置
[Router]firewall enable
[Router]acl 101
[Router-acl-101]rule deny udp source any destion any destination-port eq 1434
[Router-Ethernet0]firewall packet-filter 101 inbound
6506产品的配置：
旧命令行配置如下：
6506(config)#acl extended aaa deny protocol udp any any eq 1434
6506(config-if-Ethernet5/0/1)#access-group aaa
国际化新命令行配置如下：
[Quidway]acl number 100
[Quidway-acl-adv-100]rule deny udp source any destination any destination-port eq 1434
[Quidway-acl-adv-100]quit
[Quidway]interface ethernet 5/0/1
[Quidway-Ethernet5/0/1]packet-filter inbound ip-group 100 not-care-for-interface

5516产品的配置：
旧命令行配置如下：
5516(config)#rule-map l3 aaa protocol-type udp ingress any egress any eq 1434
5516(config)#flow-action fff deny
5516(config)#acl bbb aaa fff
5516(config)#access-group bbb
国际化新命令行配置如下：
[Quidway]acl num 100
[Quidway-acl-adv-100]rule deny udp source any destination any destination-port eq 1434
[Quidway]packet-filter ip-group 100

3526产品的配置：
旧命令行配置如下：
rule-map l3 r1 0.0.0.0 0.0.0.0 1.1.0.0 255.255.0.0 eq 1434
flow-action f1 deny
acl acl1 r1 f1
access-group acl1
国际化新命令配置如下：
acl number 100
rule 0 deny udp source 0.0.0.0 0 source-port eq 1434 destination 1.1.0.0 0
packet-filter ip-group 101 rule 0
注：3526产品只能配置外网对内网的过滤规则，其中1.1.0.0 255.255.0.0是内网的地址段。

8016产品的配置：
旧命令行配置如下：
8016(config)#rule-map intervlan aaa udp any any eq 1434
8016(config)#acl bbb aaa deny
8016(config)#access-group acl bbb vlan 10 port all
国际化新命令行配置如下：
8016(config)#rule-map intervlan aaa udp any any eq 1434
8016(config)#eacl bbb aaa deny
8016(config)#access-group eacl bbb vlan 10 port all
