Figure 82 VPN Example

In this example, the ISG50 is router X (1.2.3.4), and the remote IPSec router is router Y (2.2.2.2).

Create the VPN tunnel between ISG50 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.
