I keep gettin the Denied connection with code Result Code:0xc0040017 fwx_e_tcp_not_syn_packet_dropped whenerver i try to access an external ftp server. Clients are acting as SecureNAT and Web Proxy. I have created a rule :
From ;internal, To:External , All Users
and In configure FTP i have unchecked the Read Only option.
FTP access filter is enabled.
