Create Firewall

A firewall is a set of rules used to protect the resources of your LAN. These rules
filter the packets arriving at the router. If a packet does not meet the criteria
specified in the rule, it is dropped. If it does meet the criteria, it is allowed to pass
through the interface that the rule is applied to. This wizard enables you to create
a firewall for your LAN by answering prompts in a set of screens.
In this window, select the type of firewall that you want to create.
The router that you are configuring must be using a Cisco IOS image that
•
supports the Firewall feature set in order for you to be able to use Cisco
Router and Security Device Manager (SDM) to configure a firewall on the
router.
The LAN and WAN configurations must be complete before you can
•
configure a firewall.
Click this if you want SDM to create a firewall using default rules. The use case
scenario shows a typical network configuration in which this kind of firewall is
used.
