I set up IIS 7.5 with a FTP site that uses a SSL Certificate on port 990 to ALLOW (not REQUIRE) SSL connections.
I configured my firewall to let 990 through.
On my FTP client, I turned off PASV mode. I am then able to establish FTP connection (both command and data)
However, my customer, is not able to connect. This is part of his log..
