Using the Business Communications Manager DNS service
Consider the following guidelines when using DNS:
•
If you enable the Business Communications Manager DNS service, ensure that you configure
each workstation on the network to use Business Communications Manager as DNS server.
•
When you disable Business Communications Manager DNS service, set the DNS Server field
in DHCP configuration to the remote DNS server IP address. If DHCP service is also disabled
in Business Communications Manager, you must configure each workstation on your network
to use the remote DNS server.
To configure DNS services settings
1
On the navigation tree, click the
Services
key and click the
DNS
heading.
The DNS Summary screen appears.
2
Configure the DNS Summary attributes according to the following table.
3
Press the

Attribute
Description
Description
Allows you to view the description of the DNS server.
Version
Allows you to view the version of the DNS service.
Status
Allows you to enable or disable the DNS cache proxy in Business Communications Manager.
IP Domain
Allows you to specify the domain name that Business Communications Manager and its DHCP
clients uses. When you modify the Domain, the setting automatically copies to
Domain Name
global options under
DHCP
service.
Primary (and
Secondary)
Server
Allows you to specify the IP addresses of the primary DNS server and the secondary DNS server
in a valid dot format. When you specify a secondary DNS server, separate the two IP addresses
by a space.
The DNS cache uses the servers in the order that you specify, so make sure the IP address of the
secondary DNS server appears second.
Forward Timeout
Allows you to specify the time-out, in seconds, to resolve queries using the DNS servers that you
specify in DNS server.
Note:
The DNS proxy carries security features because it keeps all of the internal IP
addresses from external web servers. For information on other security features, see
“Configuring NAT (Network Address Translation)” on page 737
and
“Configuring IP
Firewall Filters” on page 819
