Security; Content Filtering - NETGEAR RO318 Reference Manual

Security

The Model RO318 router is equipped with several features designed to maintain security, as
described in this section.
• Stateful Packet Inspection for True Firewall Protection
Unlike simple Internet sharing routers, a firewall uses a process called stateful packet
inspection to ensure secure firewall filtering to protect your network from attacks and
intrusions.
• Logging of security incidents
You can configure the Model RO318 router to log suspicious access requests from the Internet
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 such an incident occurs.
• 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.

Content Filtering

With its content filtering features, the Model RO318 router prevents objectionable content from
reaching your PCs. Its content filtering features include:
• Content filtering by domain or keyword
The Model RO318 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.
• Logging of inappropriate use
You can configure the Model RO318 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.
