Configure local DNS service
Note: In this example of a DNS configuration, client DNS is not in use. You can, however,
protect your DNS servers from callers by defining connection-specific client DNS servers and
specifying that Connection profiles use those client servers. For information about client DNS,
see “Client DNS” on page 9-15.
To configure the local DNS service:
1 Open Ethernet > Mod Config > DNS.
2 Set the Domain Name parameter to specify the local domain name.
3 If appropriate, set the Sec Domain Name parameter to specify a secondary domain name.
4 Set the Pri DNS and Sec DNS parameters to specify, respectively, the IP address of a
primary and secondary DNS server, and set the List Attempt parameter to enable the DNS
list attempt feature. For example:
Ethernet
Mod Config
DNS...
Domain Name=abc.com
Sec Domain Name=
Pri DNS=10.65.212.10
Sec DNS=12.20 7.23.51
Allow As Client DNS=Yes
Pri WINS=0.0.0.0
Sec WINS=0.0.0.0
List Attempt=Yes
List Size=35
Client Pri DNS=0.0.0.0
Client Sec DNS=0.0.0.0
Enable Local DNS Table=No
Loc.DNSTab Auto Update=No
5 Exit the profile and, at the exit prompt, select the exit and accept option.
Creating a local DNS table
You can create a local DNS table to provide a list of IP addresses for a specific hostname when
the remote DNS server fails to resolve the hostname. If the local DNS table contains the
hostname for the attempted connection, it provides the list of IP addresses.
You create the DNS table from the terminal server by using the DNStab command to enter the
hostnames and their IP addresses. A table can contain up to eight entries, with a maximum of
35 IP addresses for each entry. If you specify automatic updating, you only have to enter the
first IP address of each host. Any others are added automatically.
Automatic updating replaces the existing address list for a host each time the remote DNS
server succeeds in resolving a connection to a host that is in the table. You specify how many
of the addresses returned by the remote server can be included in the new list.
Valid hostnames must adhere to the following rules. Each name in the local DNS table:
• Must be unique in the table.
• Must start with an alphabetic character, which can be either uppercase or lowercase.
• Must be less than 256 characters.
