Nighthawk M1 does not port forward and cannot get help from netgear

> [...] the Nighthawk M1 [...]

   I've never touched one, so I know nothing, but there seem to be
multiple variants of that model.  The actual model number (on the label
on the gizmo?) might be interesting.

   Not a very detailed description of anything.  Actual port-forwarding
rule(s)?

   "cannot" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions with their actual results (error messages, LED
indicators, ...) can be more helpful than vague descriptions or
interpretations.

   That's how I read the manual.

   I don't know what "It says refused(RST)" means.  What is "it"?  When
you do what?

   Conventional (active-mode) FTP uses ports 20 and 21.  You might get
by with only 21 if you use passive mode.  You are talking about
plain-old, insecure FTP, not some fancy-new, secure variant (SFTP, ...),
right?
