Hi.  I can't get FTP set up via my Archer A7 V5.  I am trying to set up access to a shared folder on a Synology DS220j NAS drive.  I have the shared folder set up on the DS220j with a login created specifically only for access to that folder.  FTP and SFTP are enabled on the NAS drive using default ports of 21 and 22.  I have a current NoIP DNS account which is being resolved to my IP address correctly.

On the Archer A7 I am trying to set up Port Triggering, there is no Port Forwarding option, based on a specific external port number say 12021.  I have added a PT rule to the list with Application FTP;  Triggering Port 21;  Triggering Protocol ALL;  External Port 12021;  External Protocol ALL and it is Enabled.

I'm using Filezilla FTP client which has always been pretty straightforward for me in the past.  I am missing something though as the connection is refused every time I try.  Error message is "Connection attempt failed with "ECONNREFUSED - Connection refused by server"".

Can anyone point me at the error I am obviously making somewhere?
