Restricting sites on a network

I have a network setup and I want to be able to restrict certain sites on my kid brother's computer. Is there a way for me to restrict on his pc only or would I have to restrict it on all pc's?

Dlink router...wireless
windows xp on all except his (2000)

easiest way is to do it from the router, but you'd be blocking all access
not just his.

may i ask why you want to?

Make yourself the administrator on his PC and restrict his profile to a power user. Then you can add a cyber watch program or change the internet restriction settings. Making him a power user gives him rights to install programs but not change certian settings on his computer. There is a multitude of things you can change to restrict access on his computer.

i've never used cyberwatch or any of those, so i just didn't even think of
it. nice suggestion MD

that may be your best bet for internet sites if that's all you're looking for.
all the admin you can do, as MD suggests, is definitely available, but may
not be necessary and could cause you more headaches and hassle.

Just something to think about: "Lease amount of administrative effort."

I pretty much don't want him on any porn sites etc...

easiest way is just watch the history and if he clears it tell him your going to block all internet access to his computer. To do that go to your firewall and tell it to deny access from his IP address go out on port 80, the only thing is you must assign him a static IP address.

a blanket ban like that (all porn sites) will never work 100% anyway, and
I knew that's what you meant anyway. There's some scripts/apps that
you can get (like cyberwatch) that base the blocking based on keywords
or titles and urls. But like I said, it's never 100%.

Personally, I don't think it's worth the hassle, but hey...not brother either.

Then again if you do what I said in my last post you can let him know not to go to any pron sites or you'll shut his internet access off completely. As you know Unflux port 80 is the web port, so long as the computer you want to block has a static IP address you can do anything you want to that address. Hence you could block all internet access. But the thing with what I said is you base it on the honor system and if you catch him on a porn site cut his internet access off for a month. Then turn it back on after the month is up if he still does it cut it off again and leave it off permanently

Also look at the options on the firewall and see if there is any kind of logging feature that will tell you where ip addresses are going and have the log sent to your machine.

Well I already know that he's been on these sights, some of them are in his history, some were from pop ups. So where do I go from there. He needs the net for school so I don't think taking away his access is an option either. Back to square one.

what is a static ip
does it give certain computer a certain ip address and that way you can control its connections??
