I'm trying to work out if this setup will work for me. I've had a request to setup openDNS for a home (not my own) for parental control. But what stops others connected to this network from going in and removing the DNS and therefore removing the filters?
Also, related to this, is there any way that I could remotely check that openDNS is still working and active? (that the nameservers haven't been replaced, etc.)
