8.6.5 DNS Client

Description
When a device on the LAN requests a domain name resolution, the DNS client queries an outside DNS server
and then forwards the results to the requesting device. With this feature, devices on the LAN can convert
domain names into IP addresses, and determine what domain name is associated with an IP address.
Once a domain name has been resolved, this information is temporarily stored in a local cache. If a query is
made for the same information, the PBX responds with the information stored in its cache.

Conditions
•
A primary and secondary DNS server can be specified in the WAN-side network settings. The PBX will
query the primary DNS server first. If that query fails, the PBX queries the secondary server.
•
For details about what values to use for the DNS client settings, consult the network administrator.
•
When the built-in router is enabled, it is not possible to access a DNS server at a different site over a VLAN.
Since communication over a VPN will not be possible, do not set a destination IP address in the VPN for
the following settings:
–
27.2.1 Router Configuration—Setup—[1-2-1] WAN—Connection Settings
→
Preferred DNS IP Address
→
Alternative DNS IP Address
–
28.1 Network Service—[1] IP Address/Ports
→
DNS Setting—Preferred DNS IP Address
→
DNS Setting—Alternative DNS IP Address
Either set up a DNS server at each site, or specify a DNS server on the WAN side.
