DNS Proxy
Domain Name System (DNS) provides end users with the ability to look for devices or web sites by typing
their names, rather than IP addresses. For web sur fers, this technology allows you to enter the URL (Univer-
sal Resource Locator) as text to sur f to a desired website.
The Motorola Netopia® DNS Proxy feature allows the LAN-side IP address of the Gateway to be used for
proxying DNS requests from hosts on the LAN to the DNS Ser vers configured in the gateway. This is accom-
plished by having the Gateway's LAN address handed out as the “DNS Ser ver” to the DHCP clients on the
LAN.
☛
NOTE:
The Motorola Netopia® DNS Proxy only proxies UDP DNS queries, not TCP DNS queries.
Management
Embedded Web Server
There is no specialized software to install on your PC to configure, manage, or maintain your Motorola Neto-
pia® Gateway. Web pages embedded in the operating system provide access to the following Gateway oper-
ations:
• Setup
• System and security logs
• Diagnostics functions
Once you have removed your Motorola Netopia® Gateway from its packing container and powered the unit
up, use any LAN attached PC or workstation running a common web browser application to configure and
monitor the Gateway.
Diagnostics
In addition to the Gateway’s visual LED indicator lights, you can run an extensive set of diagnostic tools
from your Web browser.
Two of the facilities are:
• Automated “Multi-Layer” Test
The Run Diagnostics link initiates a sequence of tests. They examine the entire functionality of the
Gateway, from the physical connections to the data traffic.
• Network Test Tools
Three test tools to determine network reachability are available:
Ping - tests the “reachability” of a particular network destination by sending an ICMP echo request and
waiting for a reply.
NSLookup - converts a domain name to its IP address and vice versa.
