Hi, I have installed squid2.6.3 in freebsd 5.4 as transparent proxy. I have setup transparent proxy through cisco router and freebs ipfw so that no can bypass the proxy server. When I try to browse the net without keeping the proxy address in the browser I get the following erros; 202.xx.xx.105 - - [24/Aug/2006:22:29:09 +0545] "HEAD error:invalid-request HTTP/0.0" 400 0 TCP_DENIED:NONE 2006/08/24 22:29:09| clientReadRequest: FD 23 Invalid Request 202.xx.xx.150 - - [24/Aug/2006:22:29:09 +0545] "GET error:invalid-request HTTP/0.0" 400 3481 TCP_DENIED:NONE 2006/08/24 22:29:09| clientReadRequest: FD 24 Invalid Request 202.xx.xx.105 - - [24/Aug/2006:22:29:09 +0545] "GET error:invalid-request HTTP/0.0" 400 1676 TCP_DENIED:NONE 2006/08/24 22:29:09| clientReadRequest: FD 22 Invalid Request 202.xx.xx.146 - - [24/Aug/2006:22:29:09 +0545] "GET error:invalid-request HTTP/0.0" 400 1767 TCP_DENIED:NONE 2006/08/24 22:29:09| clientReadRequest: FD 22 Invalid Request 202.xx.xx.105 - - [24/Aug/2006:22:29:09 +0545] "HEAD error:invalid-request HTTP/0.0" 400 0 TCP_DENIED:NONE 2006/08/24 22:29:09| clientReadRequest: FD 22 Invalid Request 202.xx.xx.130 - - [24/Aug/2006:22:29:09 +0545] "GET error:invalid-request HTTP/0.0" 400 1782 TCP_DENIED:NONE 2006/08/24 22:29:10| clientReadRequest: FD 22 Invalid Request 202.xx.x.146 - - [24/Aug/2006:22:29:10 +0545] "GET error:invalid-request HTTP/0.0" 400 1704 TCP_DENIED:NONE ---------------------------------------------------------------------- If i put manually the proxy server in my browser it works nicely. What;s wrong with the transparent proxy in squid2.6.3 version. Any help will be appreciated. Thank you
