Edit Site-to-Site VPN
Virtual Private Networks (VPNs) let you protect data between your router and a
remote system by encrypting traffic so that it cannot be read by others who are
using the same public network. In effect, it gives you the protection of a pr ivate
network over public lines that may be used by other organizations.
Use this window to create and manage VPN connections to remote systems. You
can create, edit, and delete VPN connections, and reset existing connections. You
can also use this window to configure your router as an Easy VPN client with
connections to one or more Easy VPN servers or concentrators.

Site-to-Site VPN Connections

VPN connections, sometimes referred to as tunnels, are created and managed
from the VPN Connections box. A VPN connection links a router in terface to one
or more peers specified by a crypto map defined in an IP Security (IPSec)
policy.You can view, add, edit, and delete the VPN connections in this list.
