If you change some settings, you may have to restart the server:
Click Yes to restart the video system and apply the new settings.
3.1.2.1 Configuring Dynamic DNS Settings
Enter the required parameters – either in the Ethernet or the PPP section – and click Save. Wait about
10 seconds. If an error occurs during the connection to the Dynamic DNS service, an error window will pop
up. At the same time, the alarm 0055 – [SYST] – DYN DNS FAILED will be set. This alarm can be viewed in
the Status window. Faults can be due to a faulty login, wrong password, or wrong host name.
To register to a Dynamic DNS service provider, the server needs access to the internet and to a DNS server
to resolve the host name of the service provider. This internet connection can be provided by the Ethernet
connection or a 3G connection. When the internet connection is only available through 3G, it is necessary to
enter the correct Provider DNS server in the Ethernet section!
Note
 If you configure a Dynamic DNS service for both the Ethernet and the PPP (3G) connection, it
is necessary to use different host names (only 1 account required, 2 host names).
 When the RMG is behind a router, the external IP address will be used by the Dynamic DNS
service. This will automatically be set by the RMG, so no changes in the XOa settings are
necessary.
3.1.2.2 Dynamic DNS Error Messages
3.1.2.2.1 Warning: Unable to determine IP address
If you receive this error message, the RMG could not resolve the service provider’s host name. Please check
the DNS server in the Ethernet section or check the internet connection of the RMG .
3.1.2.2.2 No update required
If you change settings for the Dynamic DNS, the RMS server will write a new configuration and force an
update of this configuration. Some service providers may return a message such as “No update required” or
“Attempts to change to the current address are considered abusive”. This alarm will automatically reset on
the next automated check after one minute.
Note
An error message is displayed only once. If you want to view the message once again, set the
Dynamic DNS server to None, click Save, then re-enter your DNS provider and click Save
again. Wait a few seconds and the message will reappear.
3.1.2.3 Why Use Dynamic DNS?
Dynamic DNS provides the capability for a networked device, such as a router or modem, to notify a Domain
Name System (DNS) to change, in real time, the active DNS configuration of its configured hostnames,
addresses, or other information. Thus a hostname can be used instead of the IP address, which is very
interesting for DHCP attributed IP addresses. Especially with 3G the IP address is often attributed by DHCP.
It also becomes possible to automatically update the client software.
