Hello, Using the ftps.exe command and I have noticed that it will fail while connecting to a Windows 2008R2 ftps site if using ipv6.
While we are not really using ipv6 the tunnel adaptors are enabled by default and registered in dynamic dns.
Get the message: ERROR: 'PASV ': command not understood. Use EPSV command.
If I try the same host with ipv4 address it works fine.
