Table 105 Configuration items
Item Description
Domain Name Specify the DDNS entry name, which is the only identifier of the DDNS entry.
Server
Settings
Server Provider Select the DDNS server provider, which can be 3322.org or PeanutHull.
Server Name
Specify the server name of the DDNS server for domain name resolution.
IMPORTANT:
After the server provider is selected, the DDNS server name appears
automatically. For example, if the server provider is 3322.org, the server name is
members.3322.org. If the server provider is PeanutHull, the server name is
phservice2.oray.net. Use the default server name for the server provider
3322.org. The server provider PeanutHull can use phservice2.oray.net,
phddns60.oray.net, client.oray.net, or ph031.oray.net as the server name.
Interval
Specify the interval for sending DDNS update requests after DDNS update is
enabled.
IMPORTANT:
• A DDNS update request is immediately initiated when the primary IP
address of the interface changes or the link state of the interface changes
from down to up, no matter whether the interval is reached.
• If you specify the interval as 0, your device does not periodically initiate any
DDNS update request, but initiates a DDNS update request when the
primary IP address of the interface is changed or the link state of the interface
changes from down to up.
Account
Settings
Username Specify the username used for logging in to the DDNS server.
Password Specify the password used for logging in to the DDNS server.
Other
Settings
Associated
Interface
Select an interface to which the DDNS policy is applied.
The IP address in the host name-to-IP address mapping for update is the primary
IP address of the interface.
IMPORTANT:
You can bind up to four DDNS entries to an interface.
FQDN
Specify the Fully Qualified Domain Name (FQDN) in the IP-to-FQDN mapping
for update.
• If the DDNS service is provided by www.3322.org, the FQDN must be
specified. Otherwise, DDNS update might fail.
• If the DDNS server is a PeanutHull server and no FQDN is specified, the
DDNS server updates all the corresponding domain names of the DDNS
client account. If an FQDN is specified, the DDNS server updates only the
specified IP-to-FQDN mapping.
DDNS configuration example
Network requirements
As shown in Figure 220 , Router is a Web server with the domain name whatever.3322.org.
Router acquires an IP address through DHCP. Through DDNS service provided by www.3322.org, Router
informs the DNS server of the latest mapping between its domain name and IP address.
