Really, can you buy them in bulk?
Where?

Bulk? Nah, I am getting one from a friend of mine who works at a local computer shop. The machine is a barebone, ugly case, but a nice system.

Not really. Money that actually went into the machine was 15 dollars for a power supply. The other 35 bucks was for a crimping tool and some cable. I just lumped it all together.
But you still got a good deal on that box. That's sweet!

After reading through this whole thread, I kept asking myself when someone was going to tell him "CROSSOVER CABLE!" ...but yea, glad ya figured it out.

Hm..What is the reason behind a crossover? I'm not sure I understand why it is needed in this specific problem...

Computer to computer requires a crossover cable.
I'm not sure why; I just know it does.

It's specifically for communication between two network cards without a hub. One of the four twisted pair is reversed on one side. Most networks really don't need this kind of thing except for (if I'm remembering correctly) those times when a hub doesn't have an uplink port, but you need to plug it into another hub.

I have another question.
Here's the setup:
I have 2 routable ips (1.1.1.1, 2.2.2.2)
And 2 non-routable networks (172.40.1.x, 172.40.2.x)
And 3 ethernet cards in my linux firewall.
// link to the outside
firewall ==eth0=(1.1.1.1 and 2.2.2.2)==> the internet
// internal
firewall ==eth1=(172.40.1.1)==> mach#1(172.40.1.2)
firewall ==eth2=(172.40.2.1)==> mach#2(172.40.2.2)
What I want:
// all traffic coming from eth1 to have SNAT changed the source to 1.1.1.1
mach#1(172.40.1.2) =eth1=> firewall =eth0(1.1.1.1)=> internet
// all traffic coming from eth2 to have SNAT changed the source to 2.2.2.2
mach#2(172.40.2.2) =eth2=> firewall =eth0(2.2.2.2)=> internet
Logical example:
if(outbound eth0 == true && inbound eth1 == true)
source = 1.1.1.1
elseif(outbound eth0 == true && inbound eth2 == true)
source = 2.2.2.2
I can do:
# iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 1.1.1.1
or
# iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 2.2.2.2
But I have no contol over the inbound eth.
Anyone have any experience with this?
