How to add a porn filter to your home network

How it works

Instruct your router to send all lookup requests to OpenDNS

Setup Instructions

  1. Browse to your router and log in
  2. Find the DNS configuration setting and enter the following two DNS servers:
    208.67.222.123
    and
    208.67.220.123
  3. Save and reboot your router

Some caveats

  1. Most, but not all routers allow for a DNS configuration. If yours does not you can still set the OpenDNS up on every computer your children use. If you want to do this, use the ‘The Ultimate Guide to Changing Your DNS Server’ linked below.
  2. If your children are tech savvy enough to know how to set their device up to use a specific DNS server, they can bypass the router DNS altogether. Then a DNS filter set up on the router will not work, but then, I assume, no technical solution will be able to stop them from viewing pornography if that is what they want to do.
  3. Mobile data bypasses your router altogether and goes straight to a cellphone tower. If your children switch their devices to mobile data, they can get access to any site the cellphone providers DNS allows. Some mobile providers allow you to set up a family filter option on the account. You may need to check with the provider if yours does.
  4. This filter method will also not work if you use a VPN. VPN’s use their own DNS servers and unless your VPN provider has a DNS with a family filter, this will not work for you. However, a VPN is a simple way to get around this setup in case you want specific computers on your network to get around the filter.

Talk to your children
