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 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 GR10 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 GR10 receiver will have a different IP address every time
the internet connection is established.
Another use case is a GR10 receiver behind a router in a local network, where the router is connected to
the internet and regularly gets an updated IP address. The GR10 receiver will check every 12min for a new
IP address on the router and updates the DynDNS settings when necessary.

System Requirements
The table below describes the system requirements necessary for DynDNS.
Requirement Description
DNS Server
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.
Register for a
DynDNS
account
You need to register for a DynDNS account to use this functionality. The GR10
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.
Available
ports
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.
