Site-to-Site Access with Gateway-to-Gateway VPN
A gateway-to-gateway VPN connects two or more routers using an IPsec policy to
secure traffic between two sites. Use this type of VPN if you need to connect the
network at a branch office to the network at your main office, for example.
1. Use the Basic VPN Setup page to create a VPN. Choose Gateway as the peer
type, and enter the following:
• new connection name
• pre-shared key
• remote gateway type and remote WAN IP address or fully-qualified domain
name (FQDN)
• local gateway type and local WAN IP address or FQDN
You will also need to configure the corresponding settings on the router at
the other site. See Configuring a Basic VPN, page 107.
2. If needed, edit the default settings by using the Advanced VPN Setup page.
See Configuring Advanced VPN Parameters, page 111.
Remote Access with an IPsec Client (Client-to-Gateway VPN)
In this scenario, a remote client, such as a PC running IPsec VPN client software,
initiates a VPN tunnel. The IP address of the remote PC client is not necessarily
known in advance. The gateway acts as responder. Configure this type of VPN
tunnel if you have a teleworkers who need to securely connect to your network
from their home offices, for example.
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.
1. Use the Basic VPN Setup page to quickly configure the IKE Policy and the VPN
Policy by using the standard settings. Choose VPN Client as the peer type, and
enter the other basic settings. Note that the users’ VPN client software will need
to be configured with the same Pre-Shared Key that you enter here. See
Configuring a Basic VPN, page 107.
2. To configure the settings required by the VPN client software, use the
Advanced VPN Setup page to edit the IKE Policy and the VPN Policy. For the
required settings, refer to the VPN client documentation. See Configuring
Advanced VPN Parameters, page 109.
