DNS
On the
Advanced / DNS
page, you can add DNS servers to the system.
Figure 58. The
Advanced / DNS
page.
DNS servers are used to determine the IP address from the name of a server in Intranets or the
Internet (as a rule, they are specified by an ISP or assigned by a network administrator).
The device performs the DNS relay function, i.e., it redirects the DNS requests of users to external
DNS servers. You can specify the addresses of DNS servers manually on this page, or configure the
router to obtain DNS servers addresses automatically from your ISP upon installing a connection.
!
When you use the built-in DHCP server, the network parameters (including DNS servers)
are distributed to clients automatically.
If you want to configure automatic obtainment of DNS servers addresses, deselect the
Manual
checkbox, select a WAN connection which will be used to obtain addresses of DNS servers
automatically from the
Interface
drop-down list, and click the
Change
button.
If you want to specify the DNS server manually, select the
Manual
checkbox and enter a DNS
server address in the
Name servers
list. To specify several addresses, press the
Enter
key and
enter a needed address in the next line. Then click the
Change
button.
To remove a DNS server from the system, remove the relevant line from the
Name servers
field
and click the
Change
button.
