[LARTC] 2 internet connections for 2 different purposes

[LARTC] 2 internet connections for 2 different purposes

[brooke]

I've got a linux machine (fedora core 3) with 4 network cards.

I looked at the howto and the only example that is close to what I need 
to do is section 4.2 on multiple uplink providers. I feel like I'm so 
close but just can't get my head around the final part.

Here is what I have

eth2 and eth4 connect to 2 different isps.
I want all connections the come from my dmz on eth3 to go out of my 
connection on eth4
I want all connections from my local network on eth0 to go out of my 
connection on eth2

can anyone help me out with this?
thanks in advance
Brooke

When you say you are so close but can't get your head around the final 
part... what do you mean?  Exactly what is working and what is not?  How far 
have you gotten?

Well, I found a FAQ on the site of shorewall.net site, the config files 
for the iptables setup I'm using.
http://shorewall.net/FAQ.htm#faq32
but it's not what I want to do.

So for nowI've got the incoming NAT working for the dmz network, if you 
come in eth4 on a proper address I route you to eth3 the dmz network and 
translate it to a 10.2 address.

My problem seems to be the outgoing. I don't understand how I tell all 
machines who are on the 10.1.x.x network connected via eth0 to go out of 
the ISP connected via eth2.

Also, I don't understand how I make machines on the 10.2.1.x network on 
eth3 to use the interenet connection via eth4.

anyone care to get me going in the right direction?
Thanks in advance
Brooke
