Access FTPS from behind Forefront TMG
- by Maxim V. Pavlov
I have a web server on which IIS 7 host an SSL-enabled site.
The client in am trying to connect with is behind the corporate Forefront TMG. The app is Total Commander - a file manager shell, that has the ability to connect to SSL FTP by putting a checkmark over SSL/TLS in the FTP connection settings.
When FTP Access Filter in FF is enabled, my connection attempt fails on Negociating TLS step of FTP connection. The same happens even if I enable Allow Active FTP in the filter's settings.
But when I disable the FTP Access Filter on FF completely, I am able to connect fine.
How to configure FF TMG to allow FTPS?
