I am running FTP using IIS 8 on Windows Server 2012.

I have an FTP site that I can successfully send files in using active FTP mode but if I use passive mode to the same site with the same FTP account credentials I see the file appear in the folder with a zero byte size for a second or two and then the file disappears.

This is running in an AWS environment.

I have configured a port range in the FTP Firewall Support settings on IIS for this site and the FTP server has an AWS security group with the same ports allowed inbound from any address.

Can anyone help ?

TIA
