How access the internet through another computer

post #1 of 13
Thread Starter 
I am using a computer basically as a firewall that is running windows 7 but i was wondering if someone could direct me to a tutorial on how to setup up the computer to allow the computer connected afterwards. I do have them all setup as a workgroup and ran through a router. Any ideas or direction would be great

So they are all connected to the same switch/router? Or are you setting up the firewall between your internal network and external?

The first computer needs two Ethernet ports. Share the incoming line on the firewall computer to it's second port, then connect that port to your computer.

The router/switch is the same router/switch? If so, I don't know how you would route traffic from the switch, to the computer you want to use as a firewall, back to the switch. Why not just use the router/switch as a firewall, most (if not all) have this functionality.

The following would make more sense: router < comp used as firewall < computer to connect

If you have the computer set up with 2 NICs and have the connection shared to the second, all you should need to do is set up the traffic that you want to block in the firewall.

You may also consider OSes or software that are meant to be used as routers/firewalls and could possibly use this config:
internet < router/firewall pc < switch < internal network

That's somewhat confusing and as far as I can tell pointless.

You need only to hook up your internet to the firewall PC, then connect it to your internal switch. There is no need for 2 switches.

The basics are outlined by microsoft using ICS (if thats your choice)

vista and 7 are pretty much the same afaik.

It's fairly simple and easy. Unless you want a more robust solution?

im sorry im not being clear.

this is how i have it setup:

Comcast cable modem to my Nextgear router goes to my design rig which goes has two ports. Second port goes to my Belkon router which seperates onto 4 servers. I want to figure out how to get these four online when i am in my office and on my design rig.

EDIT:
i want to have control of what goes out, and what comes in when i am working. That is the logic behind this. SO my design computer acts like a firewall

Check out software routers

Then you could:
internet < router/firewall pc < switch < internal network

You'd probably be better off with an 802.1q compatible router and managed switch.

What you've listed is pretty rigged and you likely won't get the level of control you're looking for. Easier solution would be to control a software firewall on each box. Then you could disallow traffic at the application level.
