Receiver setup: DynDNS

Background Information
The DynDNS page allows the configuration of a dynamic DNS service to ensure access to the web interface of a receiver with
a dynamic IP address. This is especially useful when the GR/GM Series receiver is accessed via mobile Internet connection
that in most case provides only dynamic IP addresses.

When to use DynDNS
The DynDNS functionality allows clients to use an Internet domain name to address a GR/GM Series receiver with a
dynamic IP address. The typical use case for this functionality is a receiver with an Internet connection via a GPRS /
mobile Internet device. In this setup the GR/GM Series receiver will have a different IP address every time the
Internet connection is established.
Another use case is a GR/GM Series receiver behind a router in a local network, where the router is connected to the
Internet and regularly gets an updated IP address. The GR/GM Series receiver will check every 12min for a new IP
address on the router and updates the DynDNS settings when necessary.

Description
To use the DynDNS service, it is necessary to have a DNS server installed in same
network as the receiver. A DNS server can find the IP address assigned to a hostname.
This is necessary because although the DNS server knows the hostname of the DynDNS
service, the IP address of the service can change. The DNS server makes it possible to
find the DynDNS server IP address, thus allowing access to the DynDNS service.
You need to register for a DynDNS account to use this functionality. The GR/GM Series
receiver allows the use of the three most common DynDNS services on the Internet. At
registration enter the hostname you want your receiver to be accessed with. Enable
wildcard use. Mail exchanger functionality is not necessary.
To use the full web interface functionality you need to apply for an APN profile that
includes the APN (access point name) and a list of open ports from your provider. Make
sure that for Email and FTP push, the required ports from your SMTP and FTP server are
available. Also make sure to change the HTTP port (Receiver setup / Web server), the
FTP control port and FTP data port range (Receiver setup / FTP server) to those open
ports available from your provider.
