Hi all, I am running a transparent proxy with the following rules: - $IPTABLES -t nat -A PREROUTING -i eth1 -s ! 10.159.2.4 -p tcp --dport 80 -j DNAT --to 10.159.2.4:3128 $IPTABLES -t nat -A POSTROUTING -o eth1 -s 10.159.2.0/24 -d 10.159.2.4 -j SNAT --to 10.159.2.1 $IPTABLES -t filter -A FORWARD -s 10.159.2.0/24 -d 10.159.2.4 -i eth1 -o eth1 -p tcp --dport 3128 -j ACCEPT When I try to access the trading site (example www.domain.com), it is accessible via port 80 and 443. But when I try to do a trading which it goes to port 81, I cant manage to do it. I get an error message in my PC. And, there is an error in squid access.log file as below. What does this mean? TCP_DENIED/411 1665 GET http://www.domain.com/control/trading.dll? - Regards, WLSiew __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
