Configuring VPNs
A VPN provides a secure communication channel (“tunnel”) between two gateway
routers or a remote PC client and a gateway router. The following types of tunnels
can be created:
• Gateway-to-gateway VPN—Connects two or more routers to secure traffic
between remote sites.
• Remote Client (client-to-gateway VPN tunnel)—A remote client initiates a
VPN tunnel. The IP address of the remote PC client is not known in advance.
The gateway acts as responder.
• Remote client behind a NAT router—The client has a dynamic IP address
and is behind a NAT Router. The remote PC client at the NAT router initiates
a VPN tunnel. The IP address of the remote NAT router is not known in
advance. The gateway WAN port acts as a responder.
Creating Cisco QuickVPN Client Users
To use the Cisco QuickVPN, you must do the following:
STEP 1 Enable remote management. See Configuring Remote Management, page 98.
STEP 2 Create QuickVPN users. See Configuring IPsec Users, page 114. After a user
account is created, the credentials can be used by the QuickVPN client.
For more information on installing and using Cisco QuickVPN, see Appendix A,
“Using Cisco QuickVPN for Windows 2000, XP, or Vista.”
Using the VPN Wizard
You can use the VPN wizard to quickly create both IKE and VPN policies. Once the
IKE or VPN policy is created, you can modify it as required.
