Configuring a DDNS policy
A DDNS policy contains the DDNS server address, port number, login ID, password, time interval,
associated SSL client policy, and update time interval. After creating a DDNS policy, you can apply it to
multiple interfaces to simplify DDNS configuration.
The URL addresses configured for update requests vary by DDNS server.
• When a DDNS client contacts a DDNS server at www.3322.org by using HTTP, the URL address for
update requests should be configured as:
http://username:password@members.3322.org/dyndns/update?system=dyndns&hostname=<h
>&myip=<a>
• When a DDNS client contacts a PeanutHull DDNS server by using TCP, the URL address for update
requests should be configured as:
oray://username:password@phservice2.oray.net
Note that:
• Replace the parameters username and password in the URL with your actual login ID and password
registered at the DDNS service provider's website.
• members.3322.org and phservice2.oray.net are the domain names of DDNS servers. The domain
names of PeanutHull DDNS servers can be phservice2.oray.net, phddns60.oray.net, client.oray.net,
ph031.oray.net, and so on. Determine the domain name in the URL according to the actual
situation.
• The system automatically fills <h> with the FQDN that is specified when the DDNS policy is applied
to the interface and automatically fills <a> with the primary IP address of the interface to which the
DDNS policy is applied. You may also manually specify an FQDN and an IP address in <h> and
<a>, respectively. After that, the FQDN that is specified when the DDNS policy is applied becomes
ineffective. For more information about applying DDNS policies, see " Applying the DDNS policy to
an interface ."
NOTE:
•
You are not recommended to change <h> and <a> in the URL address because your configuration may
be incorrect.
• The FQDN is the only identification of a node in the network. An FQDN consists of a local host name
and a parent domain name and can be translated into an IP address.
Configuration prerequisites
Visit the website of a DDNS service provider, register an account, and apply for a domain name for the
DDNS client. When the DDNS client updates the mapping between the domain name and the IP address
through the DDNS server, the DDNS server checks whether the account information is correct and
whether the domain name to be updated belongs to the account.
