Hello, I tried this rule in my script $IPTABLES -t nat -A PREROUTING -i $INTERNAL -d ! $DMZ_NET -p tcp --dport 80 -j REDIRECT --to $squid_port but it doesn't work, all my http request are redirected to the squidport, my "-d $DMZ_NET" is not seen. I just want that all my outgoing http requests are processed by squid except the http requests going to the DMZ. Can somebody help ? Thks F
