VPN
Use the VPN module to configure a Virtual Private Network (VPN) to allow secure
access to your site from other locations. Refer to these topics:

•

Introduction to VPNs
A VPN is a connection between two endpoints in different networks to allow
private data to be sent securely over a shared or public network, such as the
Internet. This tunnel establishes a private network that can send data securely
between these two locations or networks. A VPN tunnel uses industry-standard
encryption and authentication techniques to secure the data sent between the
two networks. It can be used to create secure networks linking a central office
with remote offices, telecommuters, and/or professionals on the road.
There are several ways to create a VPN connection:
•
Site to Site VPN (Gateway To Gateway), page123
•
Remote Access (Client To Gateway), page123
•
Remote Access with Cisco QuickVPN, page125
•
Remote Access with PPTP, page125

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).

You will need to configure this router with the specific IPsec policies required for
the IPsec client. You also will need to install and configure the IPsec client
software on the users’ computers.
NOTE
Consider two other remote access options:
Remote Access with Cisco
QuickVPN, page125
and
Remote Access with PPTP, page125
.
The following is an example of a client-to-gateway VPN. A business traveler
connects to the Internet from her hotel room. Her notebook computer has VPN
client software that is configured with her office’s VPN settings. She accesses the
VPN client software and connects to the VPN router at the central office. Using the
VPN, she now has a secure connection to the central office’s network, as if she
were physically connected.
Configuration tasks:
1.
Use the
VPN > Client to Gateway
page to configure the VPN tunnel with the
settings required by the third-party client, such as TheGreenbow. For
instructions, see
Setting Up a Remote Access Tunnel for VPN Clients (Client
To Gateway), page139
.
2.
Install the client software on the users’ computers.

Remote Access with Cisco QuickVPN
Users with Cisco QuickVPN software can establish a VPN tunnel to your network.
Use this option if you want to simplify the VPN setup process. You do not have to
configure VPN policies. Remote users can connect securely with the Cisco
QuickVPN client and an Internet connection. For information about the benefits and
limitations, see “Easy and Secure Access with Cisco QuickVPN” at
http://
www.cisco.com/en/US/docs/routers/csbr/app_notes/QuickVPN_an_OL-
25680.pdf
Configuration Tasks:
1.
Use the
VPN Client Access
page to add the usernames and passwords.
2.
Optionally, use the
VPN > VPN Client Access
page to generate certificates to
install on the users computers. For more information, see
Certificate
Management, page 148
.
3.
Install Cisco QuickVPN on the users’ computers. To get the software, go to
www.cisco.com/go/software
. Enter the router’s model number in the search
box and then click
Find
. In the list of links, click
Quick Virtual Private Network
(QVPN) Utility
. After downloading the software on the computer, double-click
Setup.exe
to start the installation.
4.
If you generated certificates, copy the certificate to the directory where Cisco
QuickVPN is installed, typically C:\Program Files\Cisco Small
Business\QuickVPN client.
Remote Access with PPTP
A remote user with a Microsoft computer can establish a VPN tunnel by
connecting to a PPTP server at your site. Use this option to simplify VPN setup.
You do not have to configure VPN policies on the router, and there is no need to
install a VPN client on the users’ computers. However, be aware that security
vulnerabilities have been found in this protocol.
Configuration Tasks:
1.
Use the
VPN > PPTP Server
page to enable PPTP server, set the IP address
range for clients, and enter the usernames and passwords.
2.
Distribute the user names and passwords to the users.
