The Windows' command line FTP client doesn't support PASV transfers,
which can be a problem - NetBSD's ftp defaults to PASV, which can make
the two systems behave differently (in the client role), though it would
be the ipf configuration that was lacking. If you supplied your ipf
rules people might be able to suggest if there are any problems with
them.

I don't see any mention of NAT below, just a 'subnet block', which would
sound like a purely routed setup.
