Hello,
I'm newbie and no experience but last year our organization buy CP 15400 install in front of our server zone.
Local engineer install the firewall and guide me how to manage and how to add new host(server), policy, but i'm
not very well .Last day I was installed FTP server behind the CP firewall, in that case client can accept port 21 simple FTP service but when client access the FTPs, client can't access, errors was like this (Response:425 Can't open data connection for transfer of "/" ) . So search how to solve by googling and found to open port ftp-ssl-port and ftp-ssl-data
1023,989 and 990, so follow the instruction but still error. Would you all like to fixed my error.
Best Regards,
