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.
IKE Version
IKEv1 / IKEv2
Select
IKEv1
or
IKEv2
.
IKEv1
applies to IPv4 traffic only. IKEv2 applies to both IPv4 and IPv6
traffic. IKE (Internet Key Exchange) is a protocol used in setting up security associations that
allows two parties to send data securely. See
for more information
on IKEv1 and IKEv2.
Gateway Settings
My Address
Select how the IP address of the Zyxel Device 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 Zyxel Device
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 Zyxel
Device. The IP address of the Zyxel Device 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 Zyxel Device accept IPSec requests destined for any interface address on the Zyxel
Device.
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 Zyxel Device 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 Zyxel Device changes to using
the secondary connection, the Zyxel Device 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 Zyxel Device 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 Zyxel Device and remote IPSec router must use the same
authentication method to establish the IKE SA.
