Content Filtering

With its content filtering features, the HR314 prevents objectionable content from reaching your
PCs. Its content filtering features include:
• Content filtering by domain or keyword
The HR314 uses content filtering to enforce your network's Internet access policies. The
router allows you to control access to Internet content by screening for keywords within
Website names.
• Logging of inappropriate use
You can configure the HR314 to log access to Web sites and to e-mail the log to you. You can
also configure the router to send an immediate alert e-mail message to you whenever a local
user attempts to access a blocked Web site.

Security

The HR314 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
router 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.
• Encryption of the Wireless Link
For security against eavesdropping of the wireless signal, the router supports Wired
Equivalent Privacy (WEP) data encryption with Shared Key authentication. You can also
restrict access to the wireless network by MAC address.
