CRADLEPOINT MBR1400 USER MANUAL Firmware ver. 3.4.1
6.1 Content Filtering
You have two main options for filtering content in a network created through your MBR1400.
1)Domain / URL Filter Rules: Create a list of websites that will be either disallowed (facebook.com, for example) or allowed exclusively (your company‘s website, for example).
2)OpenDNS Content Filtering: Allows several options for filtering rules.
To create Domain / URL Filter Rules, simply input one or more website domain names or URLs. By default, these websites will be disallowed as part of a Blacklist. You can change this to a Whitelist to exclusively allow these sites.
Enable Whitelist: By default, Domain / URL filters allow you to block access from your network to any external domain or website. Enabling this as a Whitelist instead will allow access to only those sites in the list, blocking all other websites. Some sites use multiple domains, so each of them would need to be added to the list to get full site functionality. The default behavior enables the Whitelist for URLs only. Select Filter by IP Addresses to use IP addresses with the Whitelist.
Filter by IP Addresses: Enabling this will cause the router to block/allow URLs by the IP addresses they point to. This option will also force all DNS traffic through the router to ensure the correct IP address is returned during a DNS lookup. Using IP address filtering with URLs is not recommended. Some URLs do not return all valid IP addresses with DNS, so these may be missed. Another possible problem is that example.com and www.example.com refer to the same website but may return different IP addresses.
