550BDynamic domain name resolution configuration example
1269BNetwork requirements
As shown in 2452HFigure 143, the firewall wants to access the host by using an easy-to-remember domain
name rather than an IP address, and to request the DNS server on the network for an IP address by using
dynamic domain name resolution. The IP address of the DNS server is 2.1.1.2/16 and the DNS server has
a com domain, which stores the mapping between domain name host and IP address 3.1.1.1/16.
Configure dynamic domain name resolution and the domain name suffix com on the firewall that serves
as a DNS client so that the firewall can use domain name host to access the host with the domain name
host.com and the IP address 3.1.1.1/16.

1270BConfiguration procedure
Before performing the following configuration, make sure that the device and the host are accessible to
each other through available routes, and that the IP addresses of the interfaces are configured as

This configuration may vary with DNS servers. The following configuration is performed on a PC running
Windows Server 2000.
1. Configure the DNS server:
a. Select Start > Programs > Administrative Tools > DNS.
The DNS server configuration page appears, as shown in
