FTP problem with Web SSL VPN

[#1]

The Web VPN seems to work OK. I can RDP to Host and the HTTP web links work OK. But I can' t get any of the FTP links to work so that I can access files on my servers. Any ideas?

What kind of FTP server? We have had a time with Windows authentication if you' re running IIS.

Yes, the server is running IIS. I get prompted for a username and password and then it quits.

We never could get this working and was told by Fortinet supprt that it would be addressed in a later release. I never could get our to authenticate.
