and for the iptables this the script:

IPTABLES -t nat -A PREROUTING -s 192.168.0.0/32 -d 0/0 -p tcp --dport 80 -j REDIRECT --to-port 3128
IPTABLES -t nat -A PREROUTING -s 192.168.0.0/32 -d 0/0 -p udp --dport 80 -j REDIRECT --to-port 3128


but i still can't use the transparent proxy :

if i restart the service the problem will occur :

Shutting down WWW-proxy squid 2007/08/10 08:12:27| parseConfigFile: line 5 unrecognized: 'httpd_accel_host virtual'
2007/08/10 08:12:27| parseConfigFile: line 6 unrecognized: 'httpd_accel_port 80'

May i have the answer from you ALL

please for your guidance

In newer versions of squid the various "httpd_accel_*" are not longer used for configuring a transparent proxy. Instead you should use just:

I have one machine that is running both squid & iptables. On that machine, I can browse the web, either setting browsers to 'direct connection' or using proxy, lan.ip.0.0:3128. But, other computers connected to lan.ip.0.0:80 cannot establish internet connections. I'm using the same iptables syntax exactly, and squid does not seem to be doing any work for computers networked to it. I have added the 'transparent' line to squid.conf and even added a second line that also doesn't help,

http_port 80 transparent

So far, the only way I've gotten internet connectivity on the LAN is by using FORWARD rules in iptables, which really defeats the purpose I intended for squid/squidGuard, which is content filtering by URI.

Thanks in advance.
