How Do I Associate a Rule with an Interface?
If you use the Cisco SDM Firewall wizard, the access and inspection rules that
you create are automatically associated with the interface for which you created
the firewall. If you are creating a rule in Additonal Tasks/ACL Editor, you can
associate it with an interface from the Add or Edit a Rule window. If you do not
associate it with an interface at that time, you can still do so later.
Step1 Click Interfaces and Connections in the left panel and click the Edit Interfaces
and Connections tab.
Step2 Select the interface that you want to associate a rule with, and click Edit.
Step3 In the Association tab, enter the rule name or number in the Inbound or Outbound
field in the Access Rule or Inspection Rule boxes. If you want the rule to filter
traffic before it enters the interface, use the Inbound field. If you want the rule to
filter traffic that has already entered the router, but may exit the router through the
selected interface, use the Outbound field.
Step4 Click OK in the Association tab.
Step5 In the Access Rules or the Inspection Rules window, examine the Used By column
to verify that the rule has been associated w ith the interface.
How Do I Disassociate an Access Rule from an Interface
You may need to remove the association between an access rule and an interface.
Removing the association does not delete the access rule. You can associate it
with other interfaces if you want. To remove the association between an access
rule and an interface, perform the following steps.
Step1 Click Interfaces and Connections in the left panel and click the Edit Interfaces
and Connections tab.
Step2 Select the interface that you want to disassociate the access rule from.
Step3 Click Edit.
Step4 In the Association tab, find the access rule in the inbound or outbound field in the
Access Rule box. The access rule may have a name, or a number.
