hi:
i have installed squid 2.5 with ubuntu 6.06
i have changed these lines in squid.conf
acl local_network src 192.168.129.0/24
http_access allow local_network
http_port 8888
evry thing is ok,evry thins works well

know i want to have a transparent proxy so i add these 4 lines to squid.conf

httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_single_host on
httpd_accel_with_proxy on

and i run this command from a terminal
sudo iptables -t nat -A PREROUTING -p TCP -i eth0 --dport 80 \-s 192.168.129.0/24 -j REDIRECT --to-ports 8888
the responce of this command is nothing no errors
but nothing works when i configure firfox to not use a proxy : i have cheked log file no requests found
please help me!it so so so urgent!heeeeeeeeeelp !

These lines concern "httpd accelerator mode". This is the use of squid to cache outgoing traffic in, e.g., a webserver and has nothing to do with a transparent proxy. What happens if you remove them?

Difficult to believe that caching is so so so urgent. After all, you can always browse the web without caching for a while if you have to.

It is urgent because i have to configure squid and make it for this week!
for the 4 lines i found it in the net to configure squid as a transparent proxy!what about iptable ? what shoold return if everything is OK?
please help me if you can and i will be thankfull!
