Hi I have the problem that all Computers from the internal net should use the proxy. I've testet iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 but after this i get a error of proxy and I don't know what's the problem. Another problem is maybe that the version of iptables I use is the version 1.2.2 Thx for help Alexander Answers could also be in german
