This window is used to define a new host for a reverse lookup zone. Follow the
steps below.
1 In the Entry Name field, specify the host portion of the IP address of this
entry.
2 In the Fully-Qualified Name Entry field, specify the domain name of the
host. Be sure to type the fully-qualified domain name of the host.
Note: The Entry Name field and the Fully-Qualified Name Entry field collectively
define a PTR Record for the selected reverse lookup zone. The PTR record is
used in a Reverse Addresses table and maps an IP address to a host name.
3 Click Add to save the new entry.
4 Click Close to exit this window.
This window is used to delete a host from the selected zone. The Hosts in
Zone field lists all the hosts currently defined within the selected zone. To
delete a host, highlight the host you want to delete and click Delete Host. You
can only delete one host at a time. Click OK to save your changes and exit the
window. (To cancel your changes, click Cancel.)
The Reconfigure DNS window allows you to completely reconfigure DNS on
your Sidewinder G2. Changes made by the DNS configuration utility take effect
immediately. You do not need to reboot the Sidewinder G2.
Table 26 summarizes the available DNS configuration options. (For more
detailed information on determining which DNS configuration best suits your
situation, refer to the Sidewinder G2 Perimeter Security Planning Guide.)
Note: Any active DNS servers on the Sidewinder G2 will be disabled during the
reconfiguration process.
Important: Any prior modifications you have made to your DNS configuration will
be lost when you save your changes. You will need to re-apply the modifications.
