DDNS

DDNS stands for Dynamic DNS, a method to update a name server in the Domain Name System.
Without going into technical details, DDNS allows you to communicate with an MR that is out in the
field where it does neither have a public (accessible from the WEB) nor a static (not changing) IP
address. The router where the MR is connected to needs a public IP address – this is the case for
most ADSL or cable TV routers you find in private houses. You have to set-up port-forwarding in
the configuration of the router to reach the MR in the network. The DDNS service makes sure that
you can access your MR through a persistent domain name (e.g. mymr.dyndns.org).
Communication with the DDNS service needs an Internet connection – check with the PING
function as described in chapter 4.3.12.
For further details, please check the web-site of the DDNS service provider of your choice, the MR
supports the following services:

dyndns

no-ip

ovh

dyndnsit

changeip

sitelutions
NOTE: Using DDNS services is possible only if your provider gives you a public IP address.
OpenVPN (see below, chapter 4.3.7) provides another solution to deal with dynamic IP addresses.
