I am having difficulty accessing my Synology DS212j via FTP using FileZilla. I have a Synology DS212j that is connected to a network switch downstairs. The switch is connected to a Apple Extreme. I enabled NAT-PMP on the Apple Extreme downstairs. The router mode is DHCP and NAT. My upstairs desktop running Windows 8 is connected directly to the second Apple Extreme. This router mode is in bridge mode. When I go to canyouseeme.org it can see my FTP port. When I go to net2ftp.com and test the port I am able to see the DS212j and its directories. When outside the home I try to connect to the DS212j using Filezilla but it fails to connect. The error is: Response: 227 Entering Passive Mode (1x7,29,628,39,216,242) Command: LIST Error: The data connection could not be established: ENETUNREACH - Network unreachable Error: Connection timed out Error: Failed to retrieve directory listing Any suggestions on what I can do so that it can connect successfully is appreciated.
