im facing so much difficulty to create a transparent proxy in my rhel server.
i have enabled the routing from my server with the following iptable rule:
iptables -t nat -A POSTROUTING -j SNAT --to-source 203.83.188.138

but i cant act squid as transparent
note that i have made changes in the following lines
http_port 3128 transparent
http_port 80 vhost
and insert a acl too.

pls help me if any?
