I’ve configured PASV port range under advanced per the documentation. I’ve forwarded the ports and everything is working great with FTPS, FTP over TLS, and all that jazz. The only thing that doesn’t work is insecure plain FTP. (i followed the guide to disable the require secure control and data checkboxes) When you try to use passive connection with insecure plain ftp, it just hangs and i get a warning that says “passive failure: http…….”.
Is there any additional configuration needed for passive plain/insecure ftp?
