Reference Manual for the Model DG814 DSL Modem Internet Gateway

Content Filtering

With its content filtering features, the Model DG814 gateway prevents objectionable content from reaching your PCs. Its content filtering features include:

•Content filtering by domain or keyword

The Model DG814 gateway uses content filtering to enforce your network’s Internet access policies. The gateway allows you to control access to Internet content by screening for keywords within Website names or newsgroup names.

•Logging of inappropriate use

You can configure the Model DG814 gateway to log access to Web sites and to e-mail the log to you. You can also configure the gateway to send an immediate alert e-mail message to you whenever a local user attempts to access a blocked Web site.

Security

The Model DG814 gateway is equipped with several features designed to maintain security, as described in this section.

•PCs Hidden by NAT

Network address translation (NAT) opens a temporary path to the Internet for requests originating from the local network. Requests originating from outside the LAN are discarded, preventing users outside the LAN from finding and directly accessing the PCs on the LAN.

•Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the gateway allows you to direct incoming traffic to specific PCs based on the service port number of the incoming request, or to one designated “DMZ” host computer. You can specify forwarding of single ports or ranges of ports.

Autosensing 10/100 Ethernet

With its internal, 4-port 10/100 switch, the Model DG814 gateway can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN interface is autosensing and is capable of full-duplex or half-duplex operation.
