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 or PPPoE/PPTP interface. The IP address of the ZyWALL
in the IKE SA is the IP address of the interface.
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 not generally recommended
as it has the ZyWALL accept IPSec requests destined for any interface address on the
ZyWALL.
Peer Gateway
Address
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.
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).
Authentication
Note: The ZyWALL and remote IPSec router must use the same authentication method
to establish the IKE SA.
Pre-Shared Key Select this to have the ZyWALL and remote IPSec router use a pre-shared key
(password) to identify each other when they negotiate the IKE SA. Type the pre-shared
key in the field to the right. The pre-shared key can be:
• alphanumeric characters or ,;.|`~!@#$%^&*()_+\{}':./<>=-"
• pairs of hexadecimal (0-9, A-F) characters, preceded by “0x”.
Type “0x” at the beginning of a hexadecimal key. For example,
"0x0123456789ABCDEF" is in hexadecimal format; “0123456789ABCDEF” is in ASCII
format. If you use hexadecimal, you must enter twice as many characters since you
need to enter pairs.
The ZyWALL and remote IPSec router must use the same pre-shared key.
