Protocol Support - NETGEAR RangeMax DG834PN Reference Manual

Reference Manual for the DG834PN RangeMax
• Diagnostic functions
The ADSL modem wireless router incorporates built-in diagnostic functions such as Ping,
DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and
reboot the ADSL modem wireless router. You can use these diagnostic functions directly from
the DG834PN when you are connected on the LAN or when you are connected over the
Internet via the remote management function.
• Visual monitoring
The ADSL modem wireless router's front panel LEDs provide an easy way to monitor its
status and activity.
• Flash erasable programmable read-only memory (EPROM) for firmware upgrades.

Protocol Support

The DG834PN supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP).
information on TCP/IP.
• The Ability to Enable or Disable IP Address Sharing by NAT
The DG834PN allows several networked PCs to share an Internet account using only a single
IP address, which may be statically or dynamically assigned by your Internet service provider
(ISP). This technique, known as Network Address Translation (NAT), allows the use of an
inexpensive single-user ISP account. This feature can also be turned off completely while
using the DG834PN if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached PCs by DHCP
The DG834PN dynamically assigns network configuration information, including IP, ADSL
modem wireless router, and domain name server (DNS) addresses, to attached PCs on the
LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies
configuration of PCs on your local network.
• DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the ADSL modem wireless
router provides its own address as a DNS server to the attached PCs. The ADSL modem
wireless router obtains actual DNS addresses from the ISP during connection setup and
forwards DNS requests from the LAN.
• Classical IP (RFC 1577)
Some Internet service providers, in Europe for example, use Classical IP in their ADSL
services. In such cases, the ADSL modem wireless router is able to use the Classical IP
address from the ISP.
