or directly enter the ip

That's what I mean. Putting a different IP address for the DNS server(s) in the client's network settings.

that's not what I mean, you could bypass DNS altogether by directly putting in IP

Really? You'd have to know the IP addresses for all the blocked sites you want to visit.

They just switch the DNS on the client.
As mentioned above, a full-featured router can be set to only allow the DNS server you choose . Another option is setting up a Windows account without administrator priveleges, which will not allow users to change the DNS settings.

Which router supports this??? I mean I can understand it being a wanted feature but I cannot understand how it would work...

edit: nvmd I take that back, after some google'ing, there apparently is a way to kinda accomplish it.

link pls?
It wasn't a specific guide or anything so I don't have a link. But basically what you would do is set a rule on the router that denies all outgoing traffic on port 53. Then add another rule that allows outbound traffic on port 53 but only when the destination is the OpenDNS address.

That still wouldn't stop one from using a DNS server with an alternate port or proxying the DNS query through an SSH tunnel or whatever, but it would definitely add a level of complexity with trying to get around the OpenDNS server.

I have recently installed Net Nanny and for the most part I find it to be pretty good. Only problem is that there are many kosher sites that are blocked too. I am sure most filters have the same problem. Is there a way to set it so that it doesn't happen?

No filter is foolproof I use K9 and am fully aware that it can be gotten around, if you are trying to get around a filter you will always be able to.

I know a guy that can break through most filters in about 10 minutes, but he is a computer whiz.

It's called reformating and you don't have to be a whiz

If the point of a filter is to to protect your kids than you will know if they are able to get around it or get rid of it because the reports will stop coming in so I there is not that much to worry about. Unless, there is a way to disable it temporarily.

Anyone can use a linux livecd/usb that will allow them to bypass the os entirely and won't touch it all so lock down the bios with a password.
