I am expecting my ADSL connection to go live today and I'm getting a bit concerned about security.
I have 4 x PC's (including a laptop) connected to a Linksys WAP/Modem/Router, I have stopped using the WAP because it stops working from time to time which is a pain.
I have temporarily installed Norton Personal Firewall on all 4 PC's to give me some protection, but this is not really a long term solution.
I have one PC, a 2.4GHz P4, that I could use as a h/w firewall, presumably with Linux rather than Windows for extra security.
I am struggling to get my head round what to connect where. I imagine the firewall PC would connect to the modem/router with one NIC and to a second router (which I have) via a second NIC using a different address range.
That effectively means that none of the PC's on the second router will be able to 'see' the network on the first router - and the Internet won't be able to see these 'internal' PC's.
If I'm correct so far then how do I browse the Internet and pick up mail and newsgroups from the PC's connected to the second router?
I am hopeful that there are some articles around that will lead me through this, can anybody point me to one that will take me through step by step?
