Hi,

I tried to run squid 3.1 with tproxy in a bridge mode, but I just receive a Connection timed out. In access.log shows this entries:

1249010814.562 11319 187.0.xxx.xxx TCP_MISS/000 0 GET http://teklimbu.wordpress.com/2007/10/11/running-a-transparent-linux-squid-bridge/ - DIRECT/teklimbu.wordpress.com
1249010999.257 182407 187.0.xxx.xxx TCP_MISS/504 4146 GET http://teklimbu.wordpress.com/2007/10/11/running-a-transparent-linux-squid-bridge/ - DIRECT/72.233.2.59 text/html

These entries were transparently redirected to Squid, but after a long time the Squid returns a error page (110 connection timed out).

I tried many ways, and nothing! The actual configuration is:
eth0(Internet)
eth1(intranet)
br0 - bridge with eth0 and eth1
kernel 2.6.30.3

ebtables -t broute -A BROUTING -i eth0 -p ipv4 --ip-proto tcp --ip-dport 80 -j redirect --redirect-target DROP

iptables -t mangle -N DIVERT
iptables -t mangle -A DIVERT -j MARK --set-mark 1
iptables -t mangle -A DIVERT -j ACCEPT
iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --tproxy-mark 0x1/0x1 --on-port 3129
ip rule add fwmark 1 lookup 100
ip route add local 0.0.0.0/0 dev lo table 100

I already tried:
cd /proc/sys/net/bridge
for i in *; do echo 0 > $i; done

Someone has an idea?

Thanks,

Tiago Resende
