Blocking internet access to machines on a network

Hi,

Are there any applications out there that can block access to the internet over a network. So from me PC i can block access to a certain computer on the network. I found Internet Access Controller 2007 but that has to be install in each individual machine and cannot block over the network.

Can anyone name me some software which does this?

Thanks in advance!

why dont you use mac filtering on your router? I know that works great, because I am using that :D

This is within a company. We have lots of switches and routers connection from a bussiness internet line. I wish it was as simple as doing mac filtering! The only way i could do this is on our wireless router but everyone who access that is allowed on the internet.

I guess you should use a proxy with authentication. With this you can block internet access and also monitor everything.

yep we use a proxy with authentication..

then we have a security group (or two in AD that has permissions to the proxy)

users are added or removed to these group depending if they have internet access or not..

and as only the proxy server can get out to the internet. then any one not in the groups are blocked.

you can also allow diffefent access depening on whaich group they are in. so you can have an unrestriced group for IT admins (letting you download and go to all sites.)

and more restricted for other uese. even doing things like blocking face book out side of break time..

for good control its a great way to go, and with a caching proxy you also reduce WAN usage

Do you know an estimated cost of Websense?

Websense is good, but expensive.  A good product I have used is untangle.  It is just as good, user friendly and very powerful.

You could also use group policy to block running the application.

There are also several OpenSource applications that can do this which are complete Linux distros you install on a multi-homed PC. They are firewall-routers, (with lots of other stuff) which can do the job for you very easily. They all have web based interfaces and you can turn off a PC via IP/MAC, set a time they can go to the Internet and lots of other stuff.

I am and have been an advocate of ClarkConnect, thier community edition. It is free. Works well and you can simply do a lot with it, including what you want to do.

Again, all you need is an older unused PC with a couple of NICs.

Question, you said you have a company network.  Is there some type of Proxy or Firewall currently protecting the network?

Comment: WebSense, SurfControl, GFI are all fine for URL filtering but if I heard your question you want to allow all axcept a few machines access the Internet.

If I knew more of what your had currently it would be easier to suggest a path forward.

Regards,
Chris

We use a product called IPRISM.  At the firewall level just create a rule to block that specific PC from port 80.

Hmmm.... without further reasoning from the asker, matrix_aash, why he wants to close this thread;

I object.

There are several good and accurate answers to his question!
