If you are unsure of your CradlePoint Series or Model number, please click here.This article was written based on firmware version 5.0.0.Symptom:This article is relevant if you’re experience one of the two symptoms below:

  1. The content filtering options in a series 3 CradlePoint router has stopped working.
  2. You have an OpenDNS account and would like to configure the router to use it.

Supported CradlePoint routers can be configured to use OpenDNS to filter Web content.  OpenDNS is a third party web filtering service that CradlePoint works closely with to provide this functionality in our routers. A customer can create an OpenDNS account to take advantage of OpenDNS features such as Content Filtering & Shortcuts.To use the OpenDNS setting you need to create an OpenDNS account.  You can create an account at and click on the Create Account link. Follow the onscreen instructions to create an account.Cause:

OpenDNS has discontinued their free content filtering service as of August 2012. This should not affect internet access of customers who currently are using OpenDNS, but content filtering will no longer work. If you would still like to have the content filtering service provided by OpenDNS, you will need to create an account and add the account credentials into your CradlePoint.Resolution:

  1. Login to the router’s setup page (login instructions).
  2. With some router models (i.e., MBR95), it will be necessary to switch from Basic Mode to Advanced Mode via the toggle button beneath the CradlePoint logo at the top left of the page.
  3. Click on the Network Settings tab then Content Filtering.
  4. Put a check in the Enable box.
  5. Enter your Open DNS account information in the OpenDNS Account Information section.
  6. Enable OpenDNS ISP Filter Bypass Algorithm if desired.
  7. Click Apply to save the changes.

              User-added image Additional Filtering Options: Force All DNS Requests To Router: Enabling this will redirect all DNS requests from LAN clients to the router’s DNS server. This will allow the router even more control over IP Addresses even when the client might have their own DNS servers statically set.

Enable OpenDNS ISP Filter Bypass Algorithm: It is possible that your Internet Service Provider (ISP) uses the port that OpenDNS is configured to access, typically port 53, which will prevent OpenDNS filtering.  If OpenDNS does not appear to be working correctly, enabling this will attempt to bypass those ports when using an OpenDNS content filtering level.
