Confi gure > Dynamic DNS 4.24
The Dynamic DNS client (DYNDNS), is used to update DNS hostnames with the current IP
address of a particular interface. It operates in accordance with the specification supplied by dyndns.
org (go to http://www.dyndns.org/developers/specs/). When the interface specified by the Interface
and Inter face # parameters connects, the client checks the current IP address of that interface and
if it differs from that obtained by the previous connection, www.dyndns.org is contacted and the
hostnames spec ified in the Hostname parameters are updated with the new address.
Using the Web Page(s)
The web page includes the following parameters:
System:
This parameter is used to identify the Dynamic DNS system containing the hostnames to be
updated and may be set to “Dynamic DNS”, “Static DNS” or “Custom DNS”.
Hostname n:
These are the hostnames to be updated.
Username:
Specifies the username to use when updating hostnames.
Password:
Specifies the password to use when updating hostnames.
Confirm password:
Enter the password again in this field to confirm it.
Interface:
Defines which interface, PPP, Ethernet or default, this DYNDNS instance is associated with (usu-
ally PPP). If set to default, the client will keep track of and use the current default route.
Interface #:
Defines which Interface # this DYNDNS instance is associated with.
Wildcards:
When this parameter is “On”, it indicates that Dynamic DNS will match DNS requests of the
form “*.hostname” where the “*” matches any text. For example if Hostname 1 was set to
“user site.dyndns.org” and the Wildcard parameter was On, then “www.usersite.dyndns.org”
would resolve to the interface address.
Supply IP address in update:
This parameter is set to “Yes” by default. When set to “No”, the interface address is not sup-
plied as part of the Dynamic DNS update. In this case, DYNDNS attempts to determine the
correct IP address by other means (e.g. IP source address). This mode would normally only be
used if the router is “behind” a NAT box.
Note:
Users should visit the www.dyndns.org web site for further information before attempting to
config ure Dynamic DNS.
