A Case for ChangoLeon

I'm installing the squid with the bridge:

to see the famous bridge using brctl can connect as client to proxy server
No need to configure network access via the server ip and port that is set in Iexplore
and Mozilla in my case is 192.168.1.1: 3128, ie
You no longer have to mess with customers


but I came out.
if it runs but configuring the network and the proxy port

here is my configuration

*******************
#eth0 red Admin
#eth1 red academica
#eth2 ADSL

ifconfig eth1 0.0.0.0 promisc up
ifconfig eth2 0.0.0.0 promisc up
brctl addbr br0
brctl addif br0 eth1
brctl addif br0 eth2
ifconfig br0 192.168.1.1 netmask 255.255.255.0 up
route add default gw 192.168.1.254 dev br0
ebtables -t broute -A BROUTING -p IPv4 --ip-protocol 6 --ip-destination-port 80 -j redirect --redirect-target ACCEPT
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-ports 3128
iptables -t nat -A PREROUTING -i eth2 -p tcp --dport 80 -j REDIRECT --to-ports 3128
iptables -t nat -A PREROUTING -i br0 -p tcp --dport 80 -j REDIRECT --to-ports 3128

**************
if it runs but I have to configure each client Iexplore and that's what they did not want

the client was transparent

here is my squid.conf

********

to see if I can clarify this.
I have to add the ip and port (squid) for each client that connects with bridge.

I do not want that
