Dynamic DNS (DynDNS) is a service that is used to map a dynamic IP address to a host name. This service is only used if you are connected to the Internet with a dynamic IP address (PPP, DHCP client) and want to offer access from the Internet to a device behind the firewall, for example if you want to run an own WEB server.
To enable the DynDNS service on Quadro, choose a provider and register at his WEB site. Then you select the Enable Dynamic DNS checkbox and enter the User Name and Password that you specified during the registration at the DynDNS provider.
Usually the DynDNS is updated whenever you open a connection to the Internet, at least once per day. But the Max Time Between Updates text field allows specifying a longer period between two updates. The values entered into this field have to be greater than 24, otherwise an error occurs: "Update interval times smaller than 24 hour are too small".
If you have chosen one of the predefined DynDNS providers, you have to select it in the Service select box. Depending on the DynDNS provider, you may have to fill in some of the text fields below:
Normally the DynDNS provider uses HTTP get requests to map dynamic IP addresses to host names. If the HTTP receive request is known to you, choose the Create Custom HTTP GET Request radio button and enter the appropriate value into the URL text field.
Most of the DynDNS providers require an authentication for security. Authentication parameters can be provided in the URL text field to be used for the HTTP get request. The Basic Authentication checkbox can be selected if no authentication parameters to be provided.
