DESCRIPTION
This is the number of an individual entry.
Enter the host names in these fields.
Select the type of service that you are registered for from your
Dynamic DNS service provider.
Select Dynamic if you have the Dynamic DNS service.
Select Static if you have the Static DNS service.
Select Custom if you have the Custom DNS service.
This option is available when Custom is selected in the DDNS Type
field. Check with your Dynamic DNS service provider to have traffic
redirected to a URL (that you can specify) while you are off line.
Select the check box to enable DYNDNS Wildcard.
Select the WAN port to use for updating the IP address of the domain
name.
Select Use WAN IP Address to have the device update the domain
name with the WAN port's IP address.
Select Use User-Defined and enter the IP address if you have a
static IP address.
Select Let DDNS Server Auto Detect only when there are one or
more NAT routers between the device and the DDNS server. This
feature has the DDNS server automatically detect and use the IP
address of the NAT router that has a public IP address.
Note: The DDNS server may not be able to detect the proper IP
address if there is an HTTP proxy server between the
device and the DDNS server.
Select this check box to enable the high availability (HA) feature.
High availability has the device update a domain name with another
port's IP address when the normal WAN port does not have a
connection.
If the WAN port specified in the WAN Interface field does not have a
connection, the device will attempt to use the IP address of another
WAN port to update the domain name.
When the WAN ports are in the active/passive operating mode, the
device will update the domain name with the IP address of whichever
WAN port has a connection, regardless of the setting in the WAN
Interface field.
Disable this feature and the device will only update the domain name
with an IP address of the WAN port specified in the WAN Interface
field. If that WAN port does not have a connection, the device will not
update the domain name with another port's IP address.
Note: If you enable high availability, DDNS can also function
when the device uses the dial backup port. DDNS does not
function when the device uses traffic redirect.
