I'm trying to restrict all the computers on a network to only be able to use OpenDNS so I can manage what sites they are allowed to access.
I can't really do this by locking users out of the network settings on an OS level so I'm trying to lock down the Airport Extreme that connects them to the web.
I understand that in theory it is possible to prevent access to other DNS servers from this article: http://www.informit.com/articles/article.aspx?p=1314012&seqNum=4
However reading around suggests that the Airport software prevents me from easily doing this.
Can anyone suggest a workaround that doesn't involve replacing the Airport with something with better admin software? :)
