Configuring VPN and Security
This chapter describes VPN configuration. It also describes how to configure 
router security, beginning with the “Configuring Security” section on page 124.
The following sections are covered:
• Configuring a Basic VPN, page 109
• Configuring Advanced VPN Parameters, page 111
• Configuring Security, page 124
A VPN provides a secure communication channel (“tunnel”) between two gateway 
routers or a remote worker and a gateway router. You can create different types of 
VPN tunnels, depending on the needs of your business. Several scenarios are 
described below. Read these descriptions to understand the options and the 
steps required to set up your VPN.
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. 
STEP 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
