Have you followed http://wiki.squid-cache.org/ConfigExamples/ and setup
the forwarding, et al, correctly?
Just so you know, I can build a proxy from a default debian install
by following one of the examples there and transparent proxying "just"
works.

Squid Running No error
and this is my iptables for squid transparent
iptables -t nat -A PREROUTING -i eth0 -s 192.168.10.10
-p tcp --dport 80 -j ACCEPT
Is that meant to be eth0 or eth1?
iptables -t nat -A PREROUTING -i eth1 -s 192.168.10/24
-p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -t filter -A FORWARD -i eth1 -s 192.168.10/24
-p tcp --dport 80 -j REJECT
what wrong with my squid.conf or iptables rules?
why transparent proxy not working, & why client must
setting using proxy in their browser if the want
using proxy
Do you have any block on -t filter -L INPUT/OUTPUT that could block this
traffic?
thaks
