Good evening everyone, Using Squid 3.3.3 on Centos 6.4. I need to be able to send FTP client traffic through an ICAP server for Data Loss Prevention (DLP) purposes. I have the following ACLs defined in squid.conf ******************************************************* acl ftp proto FTP acl ftp_port port 20 21 http_access allow ftp_port connect http_access allow ftp ******************************************************* However, when I attempt to connect to my FTP server via FileZilla, I get the following squid log: ******************************************************* 366851550.677 396 192.168.137.1 NONE/200 0 CONNECT ftp.thinkwelldesigns.com:21 - HIER_DIRECT/208.106.209.235 - ******************************************************* For its part, FileZilla reports: ******************************************************* Status: Connecting to ftp.thinkwelldesigns.com through proxy Status: Connecting to 192.168.137.128:3128... Status: Connection with proxy established, performing handshake... Response: Proxy reply: HTTP/1.1 200 Connection established Status: Connection established, waiting for welcome message... Error: Connection timed out Error: Could not connect to server ******************************************************* It seems I'm almost there, but not quite. Any help for me? Thanks, Dave
