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). 
 provides further 
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.
