Rules define how the router will respond to a particular kind of traffic. Using
SDM, you can create access rules that cause the route r to block certain types of
traffic while permitting other types, NAT rules that define the traffic that is to
receive address translation, and IPSec rules that specify which traffic is to be
encrypted. SDM also provides default rules that are used in guided configurations,
and that you can examine and use when you create your own access rules. It a lso
allows you to view rules that were not created using SDM, called external rules,
and rules with syntax that SDM does not support, called unsupported rules.
Use the Rules screen to view a summary of the rules in the router’s configuration
and to navigate to other windows to create, edit, or delete rules.

translated into valid Internet IP addresses.
IPSec Rules Rules that determine which traffic will be
encrypted on secure connections.
