Hi Techie,

I configured squid in transperant proxy and it's working fine.Now i tried it in bridge mode for that i did setup for bridge mode and it's working fine.But i can not get any http request in squid access log.i can see traffic from my bridge.
tcpdump -i br0

configure bridge:

ifconfig eth0 0.0.0.0

ifconfig eth1 0.0.0.0

brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1

Then used ebtables and ip tables for redirect port 80 traffic to port 3128 for squid caching.

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 br0 -p tcp --dport 80 \
-j REDIRECT --to-port 3128

After applying this two rules,My internet is not working at user end.And when i removed these two rules , internet is working fine at user end.

when i add above two rules.I can see packet in
iptables -t nat -L -nvx and ebtables -t broute -L --Lc command

But internet is not working at user end.

Please suggest me for the same.

Regards,
Rocky

i m having the same problem.

i m looking to deploy a linux server that reside between the network & internet.

my router has the LAN side IP as 192.168.1.1/20 & its DHCP puts gateway as 192.168.1.1 with DNS1 & DNS2 IPs.

i only want to setup squid in this linux server that can work as web cache & firewall with content blocking, in such a way that we dont have to make any changes in client systems or use any proxy config. in browsers. it should work with same gateway & dns settings.

can any1 help me out?

bye
