Hello all -- I have a working copy of squid setup -- out of the box install, no config changes except the allowed hosts. When I set my browser to use squid directly, everything works fine. However, I'm trying to redirect traffic from a specific host on my network to the squid without actually setting up the proxy in the browser using iptables. My iptables line is as follows: $IPTABLES -t nat -A PREROUTING -p tcp --dport 80 -s 192.168.1.140 -j DNAT --to-destination <external_ip>:3128 This line does route the traffic correctly, but I get an Invalid Request error from squid: ---- ERROR The requested URL could not be retrieved While trying to process the request: GET / HTTP/1.1 Host: www.google.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.5) Gecko/20060719 Firefox/1.5.0.5 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q= 0.8,image/png,*/*;q=0.5 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive The following error was encountered: * Invalid Request Some aspect of the HTTP Request is invalid.

Any ideas of how I should proceed in troubleshooting this? Kind regards, Evan Fribourg Web Application Developer Deniro Marketing mailto:evan@xxxxxxxxxxxxxxxxxxx
