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 is only makes sense if you
are connected to the Internet with a dynamic IP address (and 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 his WEB site.
The Dynamic DNS Settings page consists of 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
this field should be greater than 24, otherwise an error occurs:
“Update interval times smaller than 24 hour 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 to which he has
subscribed.
The
Host text field requires the name of the host in 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, to which 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.

Selected the Create Custom HTTP GET Request radio button switches to the custom settings of the DynDNS service. Normally, the DynDNS
provider uses HTTP get requests to map dynamic IP addresses to host names. If the user knows this HTTP get request exactly, the radio button
Create Custom HTTP GET Request together with the text field URL allows to enter it directly.
The selection enables the following optional settings:
The URL text field requires the complete request to be sent to the DynDNS server. Normally it has the format:
[http://]www.server.domain:port/scriptpath/scriptname?param1=value1&param2=value2
The request modifies the nameserver database so that the hostname will be resolved to the new IP address.
The Basic Authentication checkbox enables the encoding of the username and password entered in the text fields above and then uses the Basic
Authentication method to notify the provider about the user authentication settings.
Most of the DynDNS providers require an authentication for safety reasons. The user can do that either together with the HTTP get request in the
text field URL or select the checkbox Basic Authentication.
