3.4 Using the Wizard to Configure a VPN Policy

Refer to your User’s Guide for more background information about VPN.

1.Click VPN Wizard in the HOME screen to help you edit a VPN rule that use a pre-shared key and configure IKE settings to establish a VPN tunnel. Click Next to continue.

Enter the WAN IP address of your ZyWALL. The ZyWALL uses its current WAN IP address (static or dynamic) in setting up the VPN tunnel if you leave this field as 0.0.0.0.

Select IP Address and then enter an IP address to identify the remote IPSec router by its IP address.

Otherwise, select Domain Name and enter the domain name.

If the remote secure gateway has a dynamic WAN IP address and does not use DDNS, enter 0.0.0.0 as the secure gateway’s address. In this case only the remote secure gateway can initiate SAs.

2.Fill in the fields and click Next to continue. Use this screen to configure the IP addresses of the devices that can use the VPN tunnel. Local network refers to the devices behind the ZyWALL and remote network refers to the devices behind the remote IPSec router.

Select Single for a single IP address. Select Range IP for a specific range of IP addresses. Select Subnet to specify IP addresses on a network by their subnet mask.

Local Network

If the Local Network field is configured to Single, enter a (static) IP address on the LAN behind your ZyWALL. If the Local Network field is configured to Range IP, enter the beginning and end (static) IP address, in a range of computers on the LAN behind your ZyWALL. If the Local Network field is configured to Subnet, enter a (static) IP address and subnet mask on the LAN behind your ZyWALL.
