Confi gure > DNS Server Update
4.21
“Dynamic DNS” is supported in accordance with RFC2136 and RFC2485. This allows units to
update specified DNS servers with their IP addresses when they first connect to the Internet and at
regular intervals thereafter. The Configure > DNS Update page allows you to configure the dynam-
ic DNS Update feature to operate as required.
Using the Web Page(s)
The web page includes the following parameters:
DNS server IP address:
This parameter is used to specify the IP address of the DNS Server that you wish to use. This
server must support “DNS Update messages”. Dynamic DNS is generally offered as a subscrip-
tion based service by ISPs but it may be appropriate for you to establish your own DNS Server
if you have a large number of deployed units.
Zone to update:
When using Dynamic DNS it will be necessary for you to select or “purchase” a domain name,
e.g. “mycompany.co.uk”. This parameter should be set match this domain name.
Name to update:
This parameter specifies an identifier that is used in conjunction with the Zone to update
parame ter to uniquely identify the unit e.g. “epos33”. The Name to update and the Zone to
update together specify the full address of the unit e.g. “epos33.mycompany.co.uk”.
Update interval (s):
This parameter specifies the interval (in seconds), at which the unit will issue update messages
to the DNS server.
Username:
This parameter is used to store the username that has been allocated to you by the Dynamic
DNS service provider.
Password:
This parameter is used to store the password that has been allocated to you by the Dynamic
DNS service provider.
Confirm password:
Enter the password again in this field to confirm it.
Password is Base64 encoded:
Some Dynamic DNS servers issue passwords that are Base64 encoded, e.g. Linux base servers.
If this is the case turn this option on so that the unit correctly decodes the password before
trans mission. Note that the password is not actually transmitted as part of the message but is
used to create a “signature” that is appended to the message. If the password is issued to you as
a hexa decimal string instead of text, you must prefix the parameter with 0x.
Interface:
This parameter defines which type of interface is configured for Internet connections (usually
PPP). May also be set to use the default route if required.
Interface #:
This parameter defines which Interface instance is configured for Internet connections.
