ZyWALL USG 100/200 Series User’s Guide

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 

.

• 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 

• 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 

.

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.
