Ok all these computer related topics have got me going now. I want to know how I would intergrate a Linux box in to my network and route my Internet traffic through it to use as my firewall.

Right now I have a Netgear FVS318 Router/Firewall and a Wireless AP for my Sony PSP and Laptop.

Is it pretty simple to do this? If so I'm thinking about driving around the neighborhood and finding a computer that someone thrown out tonight.

You need two NICs (Mine matched but it may not be vital) then there is some software that you get from the internet (sorry I dont remember the name) you make up a floppy disk and just run it.

Follow the very easy steps and youre in bidness!

I have done this a long time ago.  Its not to hard to setup if you know your way around computers.  BUT when something goes wrong you better known linux pretty well.  And I don't mean using it with the GUI interface.  ALso what Linux are you thinking of using?  Mandrake is probally the easiest to start with.

Smoothwall is probably the easiest to use linux firewall I have come across.  Both to install and use.  www.smoothwall.org

Stick a couple nic's in a old box and you'll be rolling in no time.  This is not a actual full install of linux.  It is strictly a firewall.

I know Linux farely well, and can operate it without a GUI.

Fantastic solution, thank you much! I didn't want to sit through a huge install picking which packages to install and not install for a machine that will operate only as a firewall.

Does it have a SSH Package? I just want to find an old Pizza Box PC and stick it on the top of my rack and forget about it.

Yup it does.. But you need to turn it on.. i have uses it for many years in a business environment and it works awesome! it got replaced with a cisco pix per corp request..

smoothwall looks bneato, i think i may drop freesco for smoothwall.

does anyone know how to clone macs on smoothwall for the external nic? i didnt see it in any of the documentation

Well I'm jumping in the on project now. Found a decent computer Intel Celeron 766hz, 128MB RAM, 4GB HD, This should serve well as my Smoothwall Router

OpenBSD also makes an excellent transparent gateway/firewall.

To clone a MAC in Smoothwall:

edit the file /etc/rc.d/rc.netaddress.up after the two lines :

if [ "$CONFIG_TYPE" = "2" -o "$CONFIG_TYPE" = "3" ]; then 
if [ "$RED_DEV" != ""]; then
Add this line:
ifconfig $RED_DEV hw ether 00:01:02:03:04:05

Well I'm not having much luck here. Everytime I try to install it goes through a few prompts, tells me it wants to partition the drive, I tell it ok then it says

Unable to Create File system

or something very similar

I've tried two HD's both known to be good. Any ideas?

You might need to re-DL and burn the image...

There is a prepatched version of it out there as well.

Clark Connect has worked very well for me. It not only can act as a fireway/gatway/router but also includes very helpful features such as VPN, web/mail/ database server, windows file sharing, CUPS, etc. Another great feature is completely web-based administration, you can be completely unfamiliar with linux and this will be a cinch to set up.

Mine has been running for years with no problem.

I took an old P2 system - nice, because no CPU fan - unplugged the hard drive and its pretty quiet.

I boot from a cd containing Devil Linux.
The config is held on a write protected floppy.

Devil Linux comes with its own firewall setup -- I replaced that with a irewall I was a bit more familiar with, but both are based on IPTables.

The only thing I had to add was a second NIC - cost all of $20.

If the system had been slightly newer, I could have had it booting from a USB drive, then I could have thrown out the CD and Floppy drives, and had no moving parts at all.

Works very well. I set up logging to an internal Linux system, and its amazing how much crap that firewall starts, and how many penetration attempts originate from China!

I have to tell you this Smoothwall is a pile of garbage.

I've tried 3 diffrent versions and can not get any of them to install.

Smoothwall 2.0 Express: Can't repartition the Hard Drive
Smoothwall 3.0 Grizzy (Alpha): Finds Hard Drive, yet crashes when it asks me if I want to restore settings from a floppy.
Smoothwall 3.0 Corporate: Same as above

How do smoothwall/m0n0wall handle wifi? I'd love to go with a linux or bsd firewall/router, but I have to have wireless access included, with access lists and MAC filtering.

I wouldn't try smooth wall unless you want to look like this all night

ETA: Adding wireless would be a piece of cake, if you get it running. No diffrent then any other typical Wifi setup. Do you use a WAP or Wireless Router?

Meta: I've installed countless Smoothwalls, you've got some sort of a problem; and it isn't SWE. FWIW Version 3.0  Corporate Requires a key.

What hardware are you running? I can point you to the pre-patched ISO, which for some people seems to work better. The installer is identical, it just has all of the kernel/application updates put onto the image.

The Pre-patched ISO is available Here

Well it was a hardware issue believe it or not. Smoothwall didn't like my USB Keyboard about halfway through the install. When I used a PS2 keyboard that fixed my issues.

If you already have a router-based FW, why would you want to punish yourself by futzing around with Linux?
