Chapter 20 IPSec VPN
You should set up the following features before you set up the VPN tunnel.
•In any VPN connection, you have to select address objects to specify the local policy and remote policy. You should set up the address objects first.
•In a VPN gateway, you can select an Ethernet interface, virtual Ethernet interface, cellular interface, VLAN interface, or virtual VLAN interface to specify what address the ZyWALL uses as its IP address when it establishes the IKE SA. You should set up the interface first. See Chapter 10 on page 199.
•In a VPN gateway, you can enable extended authentication. If the ZyWALL is in server mode, you should set up the authentication method (AAA server) first. The authentication method specifies how the ZyWALL authenticates the remote IPSec router. See Chapter 39 on page 625.
•In a VPN gateway, the ZyWALL and remote IPSec router can use certificates to authenticate each other. Make sure the ZyWALL and the remote IPSec router will trust each other’s certificates. See Chapter 41 on page 639.
20.2The VPN Connection Screen
The VPN Connection screen lists the VPN connection policies and their associated VPN gateway(s), and various settings. In addition, it also lets you activate / deactivate and connect / disconnect each VPN connection (each IPSec SA).
To access this screen, click VPN > IPSec VPN. The following screen appears.
"Except for dynamic IPSec VPN rules, each VPN connection requires a corresponding policy route.
Dynamic IPSec VPN rules only require a corresponding policy route if you select Use Policy Route to control dynamic IPSec rules.
The VPN wizard automatically creates a corresponding policy route. If you create the VPN connection in the VPN > IPSec VPN screens, you need to manually create a corresponding policy route.
