Reference Manual for the Model CG814M Wireless Cable Modem Gateway
Configurable Auto Uplink™ Ethernet Connection
With its internal
The gateway incorporates Auto UplinkTM 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.
USB Port
A USB connection to your computer eliminates the need for installing an Ethernet card.
Protocol Support
The CG814M Gateway supports the Transmission Control Protocol/Internet Protocol (TCP/IP). Appendix B, "Networks, Routing, and Firewall Basics" provides further information on TCP/IP.
•IP Address Sharing by NAT
The CG814M Gateway 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
•Automatic Configuration of Attached PCs by DHCP
The CG814M Gateway 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.
•DNS Relay
When DHCP is enabled and no DNS addresses are specified, the gateway provides its own address as a DNS server to the attached PCs. The gateway obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.
