My FTP server is on a Windows Server 2008 running IIS 7.5.(on 10.8.39.8 in the DMZ.)
The ftp root is on another, networked server. (\\Teqfap16\ftp-server-root\" on 10.8.35.x subnet)
This works fine if encryption is disabled at the FTP server.
However, once encryption is on, "required for credentials only", the connection never manages to complete the directory listing phase. Access seems to be denied to the second server.
Server sent passive reply with unroutable address 10.8.39.8, using host address instead.
Timeout detected. (data connection)
Could not retrieve directory listing
Error listing directory '/'.
Any ideas on how to resolve this would be greatly appreciated!
