6-思科防火墙：ASA中Object-group在ACL中的应用

标签：dom   命令   line   51cto   定义   xtend   调用   ice   hash   

ASA(config-network-object)# object network yuan2
ASA(config-network-object)# subnet 202.100.1.0 255.255.255.0

ASA(config-network-object)# object network yuan3
ASA(config-network-object)# range 202.100.2.10 202.100.2.20

2、定义object-group，将上述打包在一起，还可以单独增加网段、主机：
打包：
ASA(config)# object-group network yuan
ASA(config-network-object-group)# network-object object yuan1
ASA(config-network-object-group)# network-object object yuan2
ASA(config-network-object-group)# network-object object yuan3
单独增加主机、网段：
ASA(config-network-object-group)# network-object 202.10.20.0 255.255.255.0 //单独增加网段
ASA(config-network-object-group)# network-object host 202.10.20.1 //单独增加主机

3、定义object-group network目的
ASA(config)# object-group network mude
ASA(config-network-object-group)# network-object host 10.1.1.1

4、定义object-group service ser：
ASA(config)# object-group service ser
ASA(config-service-object-group)# service-object esp
ASA(config-service-object-group)# service-object icmp
ASA(config-service-object-group)# service-object tcp destination eq ftp
ASA(config-service-object-group)# service-object udp destination eq domain

5、全局调用：
ASA(config)# access-list aa extended permit object-group ser object-group yuan object-group mude
四、验证：
ASA# show run object
object network yuan1
host 202.100.1.1
object network yuan2
subnet 202.100.1.0 255.255.255.0
object network yuan3
range 202.100.2.10 202.100.2.20

ASA# show run object-group
object-group network yuan
network-object object yuan1
network-object object yuan2
network-object object yuan3
network-object 202.10.20.0 255.255.255.0
network-object host 202.10.20.1

ASA# show run access-list //下边就1条
access-list aa extended permit object-group ser object-group yuan object-group mude

ASA# show access-list //下边一堆
