Dynamic DNS Settings
The Dynamic DNS (DynDNS) is a service that is used to map a dynamic IP address to a host name. Thus this service only makes sense if you are
connected to the Internet with a dynamic IP address (and PPP, DHCP client) and want to allow access from the Internet to a device behind the
firewall. For example, if you want to run your own WEB server.
To enable the DynDNS service on Quadro you first have to choose a DynDNS provider and register at their website.
The Dynamic DNS Settings page provides the following
components:
The Enable Dynamic DNS checkbox selection enables the
dynamic DNS service.
The User text field requires the username specified during the
registration at the DynDNS provider.
The Password text field requires the password specified during
the registration at the DynDNS provider.
The Max time between updates text field requires entering the
period between two updates (in hours). The values entered in
these fields should be greater than 24, otherwise an error
occurs: “Update interval times smaller than 24 hours are too
small”. Normally, whenever you set up a connection to the
Internet, the DynDNS is updated at least once in the period
indicated in this field.
The Use predefined service radio button leads to the manual
configuration of the DynDNS service. The selection enables the
following optional settings:
The Service drop down list contains the provider list where the
administrator needs to select the one that has been subscribed
to.
The Host text field requires the name of the host on the Internet.
The TZO Connection Type text field is used for a special
parameter required by the DynDNS provider TZO.
The DHS Cloak-Title text field is used for a special parameter
required by the DynDNS provider DHS.
The Mail Exchange text field requires the address of the e-mail
server where the DynDNS service provider will relay your e-
mails.
Attention: If this service is used, make sure, that there is port
forwarding configured for SMTP (port 25) to the internal e-mail
server.
The easyDNS Partner text field is used for a special parameter
required by the DynDNS provider easyDNS.

Selecting the Create Custom HTTP GET Request radio button switches to the custom settings of the DynDNS service. Normally, the DynDNS

The selection enables the following optional settings:
