I have same problem when running FTP.exe to iSeries via my home LAN, not
VPN.
It seems to be the router or ISP blocking something since passive FTP by
FileZilla works fine.
I have no solution but a circumvention:
Connect the PC running FTP.exe to the internet via iPhone internet
sharing feature
running phone connection rather than the wifi connection to your
home lam.
This works without any problem and verifies windows isn't the problems but
router/ISP.

Emne: FTP commands issue
I am running into a situation where an FTP session to a client's i, where
some commands work and others fail.
- Connection is via a VPN.
- FTP client is the basic Windows FTP.EXE, run in a DOS box.
- I'm able to connect and sign in using a QSECOFR level profile.
- Basic commands like CD, LCD, BIN, PWD work fine.
- Commands that access data like LS, DIR, GET, PUT have up the session for a
while and then times out:
ftp> ls
200 PORT subcommand request successful.
425 Not able to open data connection.
- According to the network admin all ports for my connection are open.
- FTP to other machines from this PC work fine.
Any idea what might be causing this? Or how to debug it? TIA.
