The ARMC/3P is reachable via the IP address of the DSL router which is dynami-
cally assigned by the provider. Since the administrator does not know the IP
address assigned by the provider, the ARMC/3P connects to a special dynamic
DNS server in regular intervals and registers its IP address there. The
administrator may contact this server as well and pick up the same IP address
belonging to the card.
The administrator has to register an ARMC/3P that is supposed to take part in the
service with the Dynamic DNS Server and assign a certain hostname to it. He will
get a nickname and a password in return from the registration process. This
account information together with the hostname is needed in order to determine the
IP address of the registered ARMC/3P.
You have to perform the following steps in order to enable Dynamic DNS:
Make sure that the LAN interface of the ARMC/3P is properly configured.
•
Enter the Dynamic DNS Settings configuration dialog as shown in Figure 79.
•
Enable Dynamic DNS and change the settings according to your needs
•
(see below).
Enable Dynamic DNS
This enables the Dynamic DNS service. This requires a configured DNS
server IP address.
Dynamic DNS server
This is the server name where ARMC/3P registers itself in regular intervals.
Currently this is a fixed setting since only dyndns.org is supported for now.
Hostname
This is the hostname of the ARMC/3P that is provided by the Dynamic DNS
Server (use the whole name including the domain, e.g. testserver.dyndns.org,
not just the actual hostname).
Username
You have registered this username during your manual registration with the
Dynamic DNS Server. Spaces are not allowed in the Nickname.
Password
You have used this password during your manual registration with the
Dynamic DNS Server.
Check time
The ARMC/3P card registers itself in the Dynamic DNS server at this time.
Check interval
This is the interval for reporting again to the Dynamic DNS server by the
ARMC/3P.
