Cisco SDM will protect the LAN with a default firewall when you select this
option. For Cisco SDM to do this, you must specify the inside and outside
interfaces in the next window. Click Next to begin configuration.
Identify the interfaces on the router so that the firewall will be applied to the
correct interface.
Select the router interface that is connected to the Internet or to your
organization's WAN.
Do not select the interface through which you accessed Cisco SDM as the outside
(untrusted) interface. Doing so will cause you to lose your connection to Cisco
SDM. Because it will be protected by a firewall, you will not be able to launch
Cisco SDM from the outside (untrusted) interface after the Firewall Wizard
completes.
Check this box if you want users outside the firewall to be able to access the router
using Cisco SDM. The wizard will display a screen that allows you to specify a
host IP address or a network address. The firewall will be modified to allow access
to the address you specify. If youspecify a network address, all hosts on that
network willbe allowed through the firewall.
Check the physical and logical interfaces connecting to the LAN. You can select
multiple interfaces.
