networking - Use specific interface for outbound connections (Ubuntu 9.04)

I have two ethernet interfaces in my computer, which is running Ubuntu 9.04. Both interfaces sport static IPs, but use separate gateways. My /etc/network/interfaces file looks something like this:

auto eth0 eth1
iface eth0 inet static
  address 10.0.0.5

  netmask 255.255.255.0
  gateway 10.0.0.1

iface eth1 inet static
  address 192.168.2.5
  netmask 255.255.255.0
  gateway 192.168.2.1

I want to have all traffic going to the internet-at-large run through eth0, but it seems to want to go through eth1. Is there a way that I can channel my general outbound traffic through eth0 instead and only use eth1 for traffic to its subnet?

The answer should be persistent; that is to say, it should survive reboot without a superuser needing to run a command after restart.

EDIT: as requested, here is the output of my route -n command:

Answer

You should only have one default gateway. If you remove the gateway line from eth1, it'll all just work (after networking is restarted).
