Setting Up FTP For Two MBLs On Same Router

I’ve search and searched and cannot find an answer to my problem.

I have two MBLs attached to a Sky Hub.  I’ve given up any hope of getting WD2GO working with Java on Windows 8.1 (if you’ve managed this please tell me how) so I decided to attempt to use FTP to access both MBLs over the net.  This is what I’ve done so far:

I’ve registered a Dynamic DNS with dyn.com

For MBL1 I’ve set up Port Forwarding in the Sky Hub from Port 21 to its static ip address.

I can access this device with ftp://dynmanicdnsaddresss:21

For MBL2 I’ve edited vsftpd.conf:

        listen_port=2121

        pasv_min_port=6000
        pasv_max_port=6099
        and run the command vsftpd restart

Set up Port Forwarding in the Sky Hub from Port 2121 to its static ip address.

I cannot connect to this device using ftp://dynamicdnsaddress:2121.  The server shows the Authentication Required dialogue. Accepts the Username and Password as valid but after several minutes displays  “425 Failed to establish connection”

I really do not know what to do next.  Any help would be greatly appreciated.

Thanks

Mike

You don’t need to change anything on the MBL.

You only need to have a different EXTERNAL port on your router.

so it’d be 

ftp://dynamcicdnsaddress:21     →  Router forwards to port 21 of MBL 1

ftp://dynamcidnsaddress:2121   →  Router forwards to port 21 of MBL 2.

Try that.

Thanks for the suggestion, TonyPh1234,  but I’m afraid it did not work.  A connection was not even established this time.
