Tracking Internet Logs/Computer with two Internet Cards

I am trying to figure out how to set this up. This is how I want it set up.

ISP ---> Computer with two cards (One card connected to the ISP/Modem) (The Second Card goes to the Router) -----> Router------ > network (The network as lots of computers on it.)

With the computer with the two cards, I want to be able to track what people are going to for websites. I want to have it set up this way, so I don’t have to deal with software on their computers. Also this will make the chance of them getting around it a lot harder.

So my question is how I go around setting up the computer with the two network cards, to be able to do what I want.

First of all, what is the purpose of the computer w/ the two nics? And why do you have a router connected to it? Is the router acting as a router, or acting as a switch?

Sounds like he's using his computer as a firewall.

Are you trying to block what people can access? What kind of router do you have? You may be able to install dd-WRT on it, which would be a less complicated method.

Yes, you could say that I am going to be using the computer as a firewall.

I first want to monitor what people are doing. Then from there, I want to be able to block access to whatever they should not be doing.

I am thinking that untangle will help me out.

What firewall software are you currently using on the computer with two nics?

I have yet to set up anything. I just have the computer and that's it.

Checkout Endian Firewall. It has a built-in web filter w/ logging so you can see exactly what sites everyone is visiting.

Alternatively, if you want to make things a little more simple, you could remove the computer w/ two nics completely, and set your router to use the OpenDNS service.

I have to agree with SandMan on this. If you want to track, filter, block, restrict, and log sites then building a hardware firewall may be the best route. I have been experimenting with Untangle. Its Lite version is free and so far perty darn good. I have mine set as a transparent bridge. From modems to , dual wan router 2. untangle firewall 3. switch. Iam getting daily reports on the activity along with noticing a big downsize on the spyware intrusions and ads. If you have a old puter laying around.. doesn't have to be anything fancy.. just needs to nics, look up untangle.com and try it out.
