Chapter 25 IPSec VPN Each field is described in the following table. Table 121 Configuration > VPN > IPSec VPN > VPN Gateway > Edit LABEL DESCRIPTION Show Advance Settings / Hide Advance Settings Click this button to display a greater or lesser number of configuration fields. General Settings VPN Gateway Name Type the name used to identify this VPN gateway. You may use 1-31 alphanumeric characters, underscores(_), or dashes (-), but the first character cannot be a number. This value is case-sensitive. Gateway Settings My Address Select how the IP address of the ZyWALL in the IKE SA is defined. If you select Interface, select the Ethernet interface, VLAN interface, virtual Ethernet interface, virtual VLAN interface, PPPoE/ PPTP interface, or auxiliary interface. The IP address of the ZyWALL in the IKE SA is the IP address of the interface. Peer Gateway Address If you select Domain Name / IP, enter the domain name or the IP address of the ZyWALL. The IP address of the ZyWALL in the IKE SA is the specified IP address or the IP address corresponding to the domain name. 0.0.0.0 is invalid. Select how the IP address of the remote IPSec router in the IKE SA is defined. Select Static Address to enter the domain name or the IP address of the remote IPSec router. You can provide a second IP address or domain name for the ZyWALL to try if it cannot establish an IKE SA with the first one. Authentication Fall back to Primary Peer Gateway when possible: When you select this, if the connection to the primary address goes down and the ZyWALL changes to using the secondary connection, the ZyWALL will reconnect to the primary address when it becomes available again and stop using the secondary connection. Users will lose their VPN connection briefly while the ZyWALL changes back to the primary connection. To use this, the peer device at the secondary address cannot be set to use a nailed-up VPN connection. In the Fallback Check Interval field, set how often to check if the primary address is available. Select Dynamic Address if the remote IPSec router has a dynamic IP address (and does not use DDNS). Note: The ZyWALL and remote IPSec router must use the same authentication method to establish the IKE SA. ZyWALL USG 2000 User's Guide 459
