Chapter 13 Content Filtering Dell Instant uses OpenDNS to implement the Content Filtering feature. OpenDNS is a Domain Name System (DNS) resolution service provider. It offers features such as misspelling correction, phishing protection, and integrated web content filtering. For more information on OpenDNS, refer http://www.opendns.com/. The Content Filtering feature allows you to create internet access policies that allow or deny user access to websites based on the website categories and security ratings. This feature is useful to:  Prevent known malware hosts from accessing your wireless network.  Improve employee productivity by limiting access to certain websites.  Reduce bandwidth consumption significantly. When this feature is enabled on Dell Instant, all external DNS requests are forwarded to OpenDNS servers. A user is allowed or denied access to a website depending on the blacklist and whitelist entries in these servers. Internal DNS requests are forwarded to the internal DNS server. This feature also enables the IAP to store or cache the responses from the OpenDNS servers. When the IAP receives an access request, it searches the cache memory. If a suitable record is found, the IAP responds accordingly instead of contacting the DNS server again. Enabling Content Filtering To enable content filtering using the Instant UI, perform the following steps: 1. At the top right corner of the Instant UI, click the Settings link. 2. Select Enabled from the Content Filtering drop-down list and Click OK. Figure 80 Enabling Content Filtering The content filtering configuration applies to all the IAPs in the Dell Instant network and the service is enabled or disabled globally across all the wireless networks that are configured in the Dell Instant.
