[squid-users] transparent proxy error

Hello!

I have a little problem with transparent proxy, i hope, you can help me.
I have a proxy server with 2 eth interfaces.
I setted up the bridge, squid, dansguardian, and iptables, this works
transparent proxy. But i have power failure and the server shut down.
When restarted the transparent proxy not working transparently. If i set
up in the browser, this working correctly.
the iptables-save is:

the bridge:

brctl addbr br0
brctl stp br0 off
brctl addif br0 eth0
brctl addif br0 eth1
ifconfig eth0 down
ifconfig eth1 down
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig br0 172.21.253.250 up
ifconfig br0 netmask 255.255.255.0
ifconfig br0 broadcast 172.21.253.255
echo "1" > /proc/sys/net/ipv4/ip_forward
route add default gw 172.21.253.254
iptables-restore /root/scripts/ipt_working

Do you have any idea?

Thanks
