[Snort-users] eth1 and eth2 Breaks Default Route

A buddy of mine asked the following question on comp.os.linux.networking, but those folks don't fully understand why an interface would want to be set to 0.0.0.0/0. If anyone can shed some light on a fix, I'd like to know. Here's the original question:
I have Red Hat 9 on an X86 with three (3) interfaces working as an IDS. eth0 is my management interface with a live IP address. eth1 and eth2 both have their IP addresses set to 0.0.0.0/0 for data collection. All IP addresses are set in /etc/sysconfig/network-scripts/ifcfg-eth?.
When the box boots up my default route is shot through eth2 (should be eth0) even though I have my GATEWAY keyword set to the gateway I want. The following are my ifcfg-eth? entries:
I added "GATEWAY=220.127.116.11" to ifcfg-eth1 and ifcfg-eth2 to see if that would fix things. It doesn't...
Q1: How do I get the system to recognize the proper gateway as specified in ifcfg-eth0?
Q2: Is there a way to tell an interface to boot in promiscous mode? I'm thinking there is a keyword that can be placed in ifcfg-eth?, but I can't find any reference to that...
