Subj : IP address keeps changing...help!

Hi all,

I'm running a Linux box on my home network mainly for purposes of NAT / 
internet sharing. Everything works fine - eth0 goes to the LAN, with an 
IP of 192.168.0.1, and eth1 goes to the cable modem, with an external 
IP. I'm also running dhcpd on eth0, to give out IP addresses and such to 
computers on my local network.

My problem is - every once in a while, it seems that eth0 will request 
an IP address from dhcpd, so it gets assigned an IP of, say, 
192.168.0.254. Since the other computers have the default gateway set to 
192.168.0.1, obviously all the computers lose their connection, and I 
have to manually log in to the box and run the command 'ifconfig eth0 
192.168.0.1' to set it back.

Here is my /etc/sysconfig/networking/devices/eth0 file:

ONBOOT=yes
USERCTL=no
PEERDNS=yes
TYPE=Ethernet
IPADDR=192.168.0.1
DEVICE=eth0
HWADDR=00:60:97:3b:69:e5
BOOTPROTO=none
NETMASK=255.255.255.0

BOOTPROTO is not set to DHCP, and it's clearly set to use 192.168.0.1. 
Even when I restart the networking system (/etc/init.d/network restart), 

it still will pull an IP address from the DHCP server after a few hours.

Is there _any_ way I can stop this from happening?

Thanks for any help anyone can offer...

Joe
