3.11.4 DHCP server
The DHCP server application automatically assigns IP addresses to DHCP
clients. Follow the steps below to enable the DHCP applications. The example
sets a DHCP server, which could service 50 DHCP clients. The available IP
addresses for DHCP clients are located from 192.168.0.2 to 192.168.0.51. In
this example, the LAN environment is configured with gateway of 192.168.0.1
and subnet mask of 255.255.255.0. The IP address of 168.95.1.1 is set as a
DNS server.
admin# setup dhcp generic active Enable
admin# setup dhcp generic ip_range 192.168.0.2 50
admin# setup dhcp generic gateway 192.168.0.1
admin# setup dhcp generic netmask 255.255.255.0
admin# setup dhcp generic name_server1 168.95.1.1
In most applications, the value of gateway IP address is the same as the LAN
IP address of GRT series. The value of name server IP address should point
towards a valid host that provides DNS lookup service. These parameters
should be configured correctly, or computers on the LAN may not access
Internet.
Note: If the DNS proxy has been configured properly, the “name_server1” field in the above DHCP configuration
should be set with the LAN IP address of GRT series.

3.11.5 DNS proxy
DNS is the naming system for IP based networks and the naming service that
is used to locate computers on the Internet. A DNS proxy receives DNS
request from computers on the LAN, translates them into the encoding on DNS
protocol, and forwards to the real DNS server. To enable the DNS proxy,
please correctly set up the DNS proxy so that it can point towards real DNS
servers on the Internet. The following example shows you how to setup the IP
