It’s free, and allows you to register your subnets so that you can filter URLs, and more… pretty neat, no extensive configuration just setup your DNS cache or client computers to point to their DNS servers.
Although if you’re users are smart enough they could just bypass the cache by specifying different caching servers on their client… The work around to this would be to block all DNS traffic unless it goes to your DNS cache (or OpenDNS’s cache depending on how your network is configured).
but it don’t solve my problem… i have a company that want some computers only to access certain websites. other computers to have full access to the web.
i will install a RB150.
the person that will add and remove websites from the mikrotik doesn’t know anything about computers jajaaa and i don’t want to teach how to obtain the ip associated to a website and allow it in the firewall, etc, etc, etc…
i want something more easy, like use domain names instead of ips
