BODi rS BD1000 User Manual
6 • Configuring Inbound Access & NAT Mappings
An A record may be automatically added for the SOA records with a Name Server IP Address provided.
Table 31. DNS: A Records
Field
Description
Host Name
Specifies the A record of this sub-domain to be served by the BD1000. The wildcard charac-
ter “*” is supported. The IP addresses of
“
.domain.name”
will be returned for every name
ending with “
domain.name”
except names that have their own records.
TTL
Specifies the time-to-live of this record in external DNS caches.
In order to reflect any dynamic changes on the IP addresses in case of link failure
and recovery, this value should be set to a smaller value. E.g. 5 secs, 60 secs, etc.
Priority
Specifies the priority of different connections.
Select the
Default
option to apply the
Default Connection Priority
(refer to the
main DNS Settings page) to an A record. To customize priorities, choose the Custom
option and a priority selection table will be shown at the bottom.
Included IP
Address(es)
Specifies the WAN-specific Internet IP addresses that are candidates to be returned
when the BD1000 responds to DNS queries for the domain name specified by Host
Name.
The IP addresses listed in each box as
default
are the Internet IP addresses associ-
ated with each of the WAN connections. Static IP addresses that are not associated
with any WAN can be entered into the Custom IP list. A PTR record is also created
for each Custom IP.
For WAN connections that operate under Drop-in mode, there may be other
routable IP addresses in addition to the
default
IP address. Therefore, the BD1000
allows custom Internet IP addresses to be added manually via filling the text box on
the right-hand side and clicking the + button.
Only the checked IP addresses in the lists are candidates to be returned when
responding to a DNS query.
In case a WAN connection is down, the corresponding set of IP addresses will not
be returned. However, the IP addresses in the Custom IP field will always be
returned.
If the Connection Priority field is set to
Custom
, you can also specify the priority of
the use of each WAN connection. Only selected IP address(es) of available connec-
tion(s) with the highest priority, and also Custom IP addresses will be returned. By
default, the Connection Priority is set to
Default
.
