>>> and when a try to connect using transparent proxy, and >>> error is shown in access.log:
>>> TCP_DENIED/403 1044 CONNECT 200.170.45.6:7773 - NONE/- - >> Post your squid.conf (without blank lines or comments). > Sorry my late response: By default Squid only allows the CONNECT method to two well-known SSL ports. This to prevent abuse of the proxy server via the connect method. There are two ways to fix this: 1) Change this line acl SSL_ports port 443 563 to acl SSL_ports port 443 563 7773 2) Create an acl to match this site acl some_site dst 200.170.45.6 http_access allow CONNECT some_site Put the http_access line before this line in squid.conf http_access deny CONNECT !SSL_ports I would recommend #2. It is more work to setup, but it is more secure. Adam
