Introduction 1-3
Content Filtering
With its content filtering feature, the DG824M prevents objectionable content from reaching your
PCs. The gateway allows you to control access to Internet content by screening for keywords
within Web addresses. You can configure the gateway to log and report attempts to access
objectionable Internet sites.
Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the DG824M 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 gateway 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 PC 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.
Protocol Support
The DG824M supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP).
Appendix B, “Network and Routing Basics ” provides further
information on TCP/IP.
• IP Address Sharing by NAT
The DG824M 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.
• Automatic Configuration of Attached PCs by DHCP
The DG824M dynamically assigns network configuration information, including IP, gateway,
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.
