اما کلاینت‌ها این پیغام را دریافت می‌کنند:

کسی می‌داند مشکل کجاست؟

[tolstoy]

شما تنظیمات iptables مربوط به redirect کردن ترافیک و transparent proxy رو انجام دادید؟

[reza_bagheri]

بله این هم اسکریپت iptables من:
#!/bin/sh
IPTABLES=/sbin/iptables
$IPTABLES -F

$IPTABLES -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128
$IPTABLES -A POSTROUTING -t nat -o ppp0 -j MASQUERADE

echo 1 > /proc/sys/net/ipv4/ip_forward
echo Starting Internet Connection Sharing...

اینو بخونید: http://www.cyberciti.biz/tips/linux-setu...howto.html.
کامله.
اینم مثال‌هایی از تنظیمات Squid:
http://wiki.squid-cache.org/ConfigExamples

[reza_bagheri]

لینکی که ارسال کرده اید مربوط به squid 2.6 است و در squid 2.7 بخش transparent proxy تغییر کرده است...
فکر می‌کنم مشکلم دقیقا همین حا باشد در Transparent proxy، چون وقتی با پروکسی کار می‌کنم هیچ مشکلی وجود ندارد.
