Problem solved, clearly I used the wrong option for build.... I tried make clean and rebuild with --enable-linux-netfilter only and it works fine

Somehow it doesn't seem to work correctly. When it runs, it shows that it is running in transparent mode, but then when HTTP requests hit the box it gives the WARNING: Transparent proxying not supported. The web browser shows an error page but from the squid itself (Error: HTTP 400 Bad Request - Invalid URL.....). When I configured the build, I used the tproxy and the netfilter options for transparent proxying as I wasn't sure what one I needed. Does anyone have a clue why it will not run in transparent mode. I am pretty sure my iptables is OK Here is what the trace shows: No. Time Source Destination Protocol Info 20 12.102354 192.168.26.128 192.168.130.250 HTTP GET / HTTP/1.1 Frame 20 (493 bytes on wire, 493 bytes captured) Ethernet II, Src: 00:0c:29:e8:3d:07, Dst: 00:0c:29:01:ce:bc Internet Protocol, Src Addr: 192.168.26.128 (192.168.26.128), Dst Addr: 192.168.130.250 (192.168.130.250) Transmission Control Protocol, Src Port: 44418 (44418), Dst Port: http (80), Seq: 1, Ack: 1, Len: 427 Hypertext Transfer Protocol GET / HTTP/1.1\r\n Host: 192.168.130.250\r\n User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.1) Gecko/20060313 Fedora/1.5.0.1-9 Firefox/1.5.0.1 pango-text\r\n Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plai n;q=0.8,image/png,*/*;q=0.5\r\n Accept-Language: en-us,en;q=0.5\r\n Accept-Encoding: gzip,deflate\r\n Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n Keep-Alive: 300\r\n Connection: keep-alive\r\n \r\n No. Time Source Destination Protocol Info 22 12.157274 192.168.130.250 192.168.26.128 HTTP HTTP/1.0 400 Bad Request (text/html)[Short Frame] Frame 22 (1514 bytes on wire, 500 bytes captured) Ethernet II, Src: 00:0c:29:01:ce:bc, Dst: 00:0c:29:e8:3d:07 Internet Protocol, Src Addr: 192.168.130.250 (192.168.130.250), Dst Addr: 192.168.26.128 (192.168.26.128) Transmission Control Protocol, Src Port: http (80), Dst Port: 44418 (44418), Seq: 1, Ack: 428, Len: 1448 Hypertext Transfer Protocol HTTP/1.0 400 Bad Request\r\n Server: squid/3.0.STABLE1\r\n Mime-Version: 1.0\r\n Date: Thu, 14 Feb 2008 04:44:37 GMT\r\n Content-Type: text/html\r\n Content-Length: 1447\r\n Expires: Thu, 14 Feb 2008 04:44:37 GMT\r\n X-Squid-Error: ERR_INVALID_URL 0\r\n X-Cache: MISS from localhost.localdomain\r\n Via: 1.0 localhost.localdomain (squid/3.0.STABLE1)\r\n Proxy-Connection: close\r\n \r\n TIA Alan
