Configure DNS Servers
Digi TransPort User Guide 342
When the default route changes
Interface x,y becomes active
The two radio buttons determine when the update is sent, such as when the default route
changes or when the specified interface becomes active. The drop-down list offers the options
of PPP or Ethernet and the text box is used to enter the instance number for the specified
interface.
Also send an update every h hrs, m mins, s secs
The interval at which the router will issue 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 that has been allocated by the Dynamic DNS service provider.
DNS Server Password
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
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 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 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.
