Reference Manual for the ADSL Modem Wireless Router DG834G
Introduction 2-5
v1.0, October 2006
• Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The modem router contains a client that can
connect to many popular Dynamic DNS services to register your dynamic IP address.
• Universal Plug and Play (UPnP)
UPnP is a networking architecture that provides compatibility between networking
technologies. UPnP compliant routers provide broadband users at home and small businesses
with a seamless way to participate in online games, videoconferencing and other peer-to-peer
services.
Virtual Private Networking (VPN)
The ADSL Modem Wireless Router provides a secure encrypted connection between your local
area network (LAN) and remote networks or clients. It includes the following VPN features:
• Supports 5 VPN connections.
• Supports industry standard VPN protocols
The ADSL Modem Wireless Router supports standard Manual or IKE keying methods,
standard MD5 and SHA-1 authentication methods, and standard DES and 3DES encryption
methods. It is compatible with many other VPN products.
• Supports 3DES encryption for maximum security.
• VPN Wizard based on VPNC recommended settings.
Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the DG834G v3 can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and
capable of full-duplex or half-duplex operation.
The modem router incorporates Auto Uplink
TM
technology. Each local Ethernet port will
automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’
connection such as to a computer or an ‘uplink’ connection such as to a switch or hub. That port
will then configure itself to the correct configuration. This feature also eliminates the need to
worry about crossover cables, as Auto Uplink will accommodate either type of cable to make the
right connection.
