Site-to-Site VPN

The help topics in this section describe the Site-to-Site configuration screens.
A Virtual Private Network (VPN) lets you protect traffic that travels over lines that
your organization may not own or control. VPNs can encrypt traffic sent over
these lines and authenticate peers before any traffic is sent.
You can let Cisco Router and Security Device Manager (SDM) guide you through
a simple VPN configuration by clicking the VPN icon. When you use the Wizard
in the Create Site-to-Site VPN tab, SDM provides default values for some
configuration parameters in order to simplify the configuration process.
