PIX/ASA

PIX

Router

ACL的格式

使用netmask

access-list test extended permit ip host 1.1.1.1 120.1.1.0 255.255.255.0

使用wildcard mask

access-list 100 permit ip host 1.1.1.1 120.1.1.0  0.255.255.255

应用ACL

在全局应用

access-group test in interface inside

在接口下应用

Access-group 100 in

作用范围

只对穿越的流量有效,并且只匹配无状态信息的数据包

所有到达该接口的流量都会先经过acl的检查,然后才会送到接口做进一步处理
