A fictional one.  :-)

Here's what we are thinking about doing, with the actual subnets:

  NIC 1, eth0, 192.168.1.0, private LAN
  NIC 2, eth1, 192.168.10.0, DMZ
  NIC 3, eth2, 192.168.11.0, DMZ located elsewhere
  NIC 4, eth3, 10.0.0.0, backup subnet
  NIC 5, eth4, some-other-subnet-that-leads-to-the-internet

Ok, given the above configuration, and as we discussed before, why is it
inconceivable that the interface would communicate with my router?

Thanks for your help so far,

Erik.

Note: currently, we only have one small firewall with a LAN behind it.
The reason we need this quite elaborate setup (assuming we're not going
to buy any switches) is that we are moving part of our infrastructure to
a colocation.
