Configure DNS servers and Dynamic DNS
Also send an update every h hrs, m mins, s secs
The interval at which the router issues update messages to the DNS server.
The DNS server should delete all previous records
When enabled, causes the DNS server to delete all records of previous addresses served to the
router.
DNS Server Username
The username allocated by the Dynamic DNS service provider.
DNS Server Password
The password 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;
it appears in a signature appended to the message. If the password is issued as a hexadecimal
string and not straight text, you must use the prefix 0x in the password text box.
Confirm DNS Server Password
Enter the password in this text box to confirm it.
Local time offset from GMT
Auto detect
These two radio buttons control whether 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 automatically applies the
correction. When Auto detect is not selected, select the correct offset from the drop-down list.
Required Time Accuracy
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
How long a router that resolved the address is allowed to cache that address.
