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 re-

quest 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

addresses of real DNS servers:

admin# setup dns_proxy 168.95.1.1 168.95.192.1 140.92.61.55

Note: For PPP connections, GRT-101 will get DNS server IPs from ISP and assign them into DNS proxy automatically

if they have been pre-configured by the local ISP.

The maximum number of DNS servers is limited to 3. To save your changes,

GRT-101 has two types of WAN ports: physical WAN port (SHDSL) and logical

WAN ports (WAN 1~8). The physical WAN port connects GRT-101 to the WAN.

The logical WAN port or ports allow you to create virtual WAN connections for

plural destinations. When configuring the physical WAN port, you can change

the SHDSL physical layer protocol setting. To configure logical WAN ports, you

must provision ATM virtual connections for each logical connection. The in-

structions for each are shown below.
