[olug] More DHCP Help

Okay, this is a followup to my earlier question on DHCP.

I got the DHCP client working. But, lets begin with the problems.

Problem 1: DHCP attempts to query eth0, eth1, and lo for an address.
I want it to only list on eth0, my so-called WAN port (ie the one
connected to @home). I want this to work better.

Problem 2: I want to run a DHCP server on eth1. This will handle all the
masqueraded machines.  I have modified the init script to start dhcp
like this: "dhcp eth1" to have it start on eth1.

Now, I try to start the dhcp server and get this:

    No subnet declaration for eth1 (0.0.0.0).
    Please write a subnet declaration in your dhcpd.conf file for the
    network segment to which interface eth1 is attached.
    exiting.

Here is what is in my dhcpd.conf:

# option definitions common to all supported networks...
option domain-name "blvue1.ne.home.com";
option domain-name-servers 24.3.232.33, 24.3.232.34;

option subnet-mask 255.255.255.224;
default-lease-time 600;
max-lease-time 7200;

subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.100 192.168.1.200;
}

Okay, now, what do I need to fix to get this working right? Im running
out of time to get my @home-mandated reconfiguration done.
