Issues with Bridging

I get the error "eth1: received packet with  own address as source address"
I get this with both interfaces in my bridge.  I am starting the bridge
using the initialize.fw script that comes with nocat auth.  I get a flood of
network traffic that shuts down my network too.  I don't know why it is
doing that, any ideas?  I have both of the bridge interfaces plugged into
the same switch, is this a problem?
 
Here is how I start my bridge:
# Setup some of the variables first
BR_IP="192.168.1.253"
BR_IFACE=br0
LAN_BCAST_ADDRESS="192.168.1.255"
FWINET_IFACE="eth2"
FWLAN_IFACE="eth1"
FWLO_IFACE="lo"
LO_IP="127.0.0.1"
IPTABLES="/sbin/iptables"
 
#
# Take down the interfaces before setting up the bridge
#
ifdown $FWINET_IFACE
ifdown $FWLAN_IFACE
ifconfig $FWINET_IFACE 0.0.0.0
ifconfig $FWLAN_IFACE 0.0.0.0
 
# let's start the bridge
# This will create a new interface
brctl addbr $BR_IFACE
 
# and add the interfaces to it
brctl addif $BR_IFACE $FWINET_IFACE
brctl addif $BR_IFACE $FWLAN_IFACE
 
# make us visible to the network again
ifconfig $BR_IFACE $BR_IP
