In this example, the ZyWALL is router X (1.2.3.4), and the remote IPSec router is
router Y (2.2.2.2). Create the VPN tunnel between ZyWALL X’s LAN subnet
(192.168.1.0/24) and the LAN subnet behind peer IPSec router Y (172.16.1.0/
24).
7.4.1 Set Up the VPN Gateway
The VPN gateway manages the IKE SA. You do not have to set up any other
objects before you configure the VPN gateway because this VPN tunnel does not
use any certificates or extended authentication.
1 Click Configuration > VPN > IPSec VPN > VPN Gateway, and then click the
Add icon.
2 Enable the VPN gateway and name it (“VPN_GW_EXAMPLE”). For My Address,
select Interface and wan1. For the Peer Gateway Address, select Static
Address and enter 2.2.2.2 in the Primary field. For the Authentication, Select
Pre-Shared Key and enter 12345678. Click OK.
