The values in these text boxes specify the interval at which the unit will issue update messages
to the DNS server.
The DNS server should delete all previous records
When checked, this checkbox causes the DNS server to delete all records of previous
addresses served to the unit.
DNS Server Username
The value in this text box is the username that has been allocated by the Dynamic DNS service
provider.
DNS Server Password
The value in this text box is the password that has been allocated by the Dynamic DNS service
provider.
Password is Base64 encoded
Some Dynamic DNS servers issue passwords that are Base64 encoded, such as Linux Base
servers. If this is the case, check this check box to switch on the Base64 decoding of the
password before transmission. 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 as a hexadecimal string and not straight text, the password in the password text box
must be given the prefix 0x.
Confirm DNS Server Password
The password should be entered into this text box to confirm it.
Local time offset from GMT
Auto detect
The two radio buttons here control whether or not the offset of the local time from GMT
should be auto-detected or specified. This feature is required since a GMT timestamp must be
included as part of the authentication message. When set to auto-detect the router will
automatically apply the correction. When auto detect is not selected, the correct offset should
be selected from the drop-down list.
Required Time Accuracy
The value in this text box specifies the permitted variance between the router's time and that
of the DNS server. If the time difference exceeds this limit, the DNS update will fail.
Allow DNS clients to cache this entry for s seconds
The value in this text box specifies how long a router that resolved the address is allowed to
cache that address for.
