Site to Site VPN (Gateway To Gateway)
In a site-to-site or gateway-to-gateway VPN, a VPN router at one office connects
to a VPN router at a remotely located office. Client devices can access network
resources as if they were all at the same site. This model can be used for multiple
users at a remote office.
In the following example, the main office (Site A) and a remote office (Site B) are
connected by a VPN tunnel. Users at both sites have access to the network
resources at both sites.
Configuration tasks:
Use the VPN > Gateway to Gateway page to configure the VPN tunnel. For
instructions, see Setting Up a Gateway to Gateway (Site to Site) VPN,
page 130. For more details and examples, see Appendix D, “Configuring a
Gateway-to-Gateway VPN Tunnel Between RV0xx Series Routers.”
Remote Access (Client To Gateway)
In a remote access or client-to-gateway VPN, a computer with VPN client software
connects to a VPN router. For this scenario, you can install third-party VPN client
software on the users’ computers. Alternatively, a VPN tunnel can be accessed
from any computer with the built-in IPSec Security Manager (Windows 2000,
Windows XP, and Windows 7).
