It seems to me that our NAT router and the firewall has been set up correctly. However, Filezilla doesn't ever connect to Windows servers, but Unix servers work fine.
WHY? What could possibly be incorrect so that, while sftping to a Unix server works all the time, Windows servers time out all the time. FileZilla's Network configuration wizard... has never worked bc, I'm guessing, it is hosted on a Windows server. (After it failing and clicking Next>Finish it warns that the wizard failed, but saves the info/settings set.)
from the wizard:
We are running Filezilla Client 3.42.1, if you didn't get that from the wizard's PASS, and it's on a Windows 7 machine. However, a Windows 10 machine in our house, fails to connect to the Windows servers too. It must be a router problem then, right? If so, does anyone have any clue as to what may be good to set or change on a router to enable ftping to Windows servers?Connecting to probe.filezilla-project.org

edit: changed the start of the title from FTP to SFTP, bc just figured out that FTP does work to windows servers. Sorry for the title mess up.
