Content Filtering
With its content filtering features, the Model RP114 router prevents objectionable content from
reaching your PCs. Its content filtering features include:
• Content filtering by domain or keyword
The Model RP114 router 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 Web URLs or newsgroup names.
• Logging of inappropriate use
You can configure the Model RP114 router 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 Model RP114 router 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.
• Packet Filtering
The Model RP114 router provides extensive packet filtering capabilities. Packets are allowed
or discarded based on their source or destination addresses, service port numbers, or raw data
patterns within the packet.
