firewall question

[cmz21]

Hello,
I have 1 pc and 1 laptop at home. I would like to load the laptop with linux and am running windows on the pc. I was thinking of using the laptop to serve as my internet firewall. My question is this - what hardware do I need to set this up. I have a DSL internet connetion and would like to have the pc continually connected.

Any thoughts would be great.

Thanks

You need an appropriate NIC to connect to the DSL and some form of networking to provide forwarding to the desktop.

You could do this by using the onboard laptop NIC and then serve the windows machine by 1) another wired NIC, 2) wireless peering, 3) some form of USB HUB/NIC device (no I don't have a recommendation!).

Every main Linux distribution would have IPTables and the ability to forward traffic to the other "network segment".

NOTE!!!! You will need to write you own routing table entries to support the other device, and perhaps enable DHCP.

NOTE!!!! Use care in the services you expose publicly on your laptop - but you knew that.

Well - I'm running in such an environment, - just without windows on the second, third pc, but linux too, and only a switch between dsl-modem and laptop.

Some people told me I need a second eth-card, but that's not true.

I found an easy (but german) howto, and had it set up in about 30 minutes (without further configuring the firewall, because there are no services running exposed to outside).
