I have installed 2 Synology DS106 in my network and enabled the FTP function. The used ports are 21 (for FTP1) & 21021 (for FTP2). The configuration of DS106(s) and port forward funtion on my router done.
For FTP1 (DS106), someone log in from outside by input ftp://domain
via IE, that's OK and can sucessfully log in and view all folders.
For FTP2 (DS106), someone log in from outside by input ftp://domain:21021
, the screen prompt to login ID and password. After input of login ID & password, no folders can be displayed and with error message "time out"
They have tried IE, cuteFTP and other FTP client software but still fail to log in. (the error message are "time-out", "10060")
Can 2 DS106(s) install in one network with both FTP functions. Any additional seetings are required except port forwarding ??
