Remote Access to FTP server not working

Hello,

Trying to set up Remote Access to a NAS i have configured as an FTP server.



Works perfect inside the network over port 2121? But out side I can never get it to work.







I also have an FTP server set up on my Windows 10 Computer with Filezilla Server running on port 21 (Forwarded in router) and that runs perfectly inside and out side my network.







My NAS is a Dlink DNS 345



My router/modem is a Netgear DGN2200v4







Have tried port forwarding the correct ports but like i said cant get it to work outside network.







Any help would be much obliged.









Please help.

Thanks!



I didn't find the right solution from the Internet.
