I cannot seem to get opendns to work. I'm have a macbook and I have 2 windows machine. When I do ipconfig on the windows machine the dns shows my router ip. I setup the router dns to point to 208.67.222.222 and 208.67.220.220 and I flushed dns. I have webfiltering on to low.

  As you configured the OpenDNS resolver addresses correctly on the WAN side, they will never be propagated to the computer, so you'll not see them there, but will see that your computer's DNS is pointed to the router.  This is good, else your local name resolution would be broken or impacted.

  What message does http://welcome.opendns.com/ come back with?

  Thanks rotblitz that was my thought but needed to talk it through. So now when I go to http://welcome.opendns.com the following comes up

  You aren't using OpenDNS yet.
  Let's fix that. If you haven't restarted your computer yet, please do that now.

  You see now what the problem is.  Your router settings don't seem to take effect.  Your ISP may redirect your DNS queries to their DNS service.  Check it with this command:

  nslookup -type=txt which.opendns.com. 208.67.220.220

  Yes, your ISP redirects your DNS queries to their own DNS service.  Your router settings cannot take effect then.

  If you still want to use OpenDNS, try with DNSCrypt: http://dnscrypt.org/
  This may be able to circumvent your ISP's DNS redirection.
