Hey Experts,
I am running into a bit of a situation trying to get the encryption in Filezilla working.

What i have is a filezilla server on version 9.4.0
Running on Server 2008R2 with windows firewall off.
FTP is configured for port 211
I have a Sonicwall router.

If i have the "Enable FTP over SSL/TLS Support" turned off i can connect up just fine.
If i turn that on, and on the Filezilla client choose "Require explicit FTP over TLS" It logs in i accept the certificate but then i get
Response:      425 Can't open data connection.
Error:      Failed to retrieve directory listing

I have read all kinds of articals saying to check my network configuration.  I have checked it a thousand times and since it works with SSL/TLS off i would think it has to be correct.

My passive mode ports are 3000-4000 and i have those forwarded the same was i do 221.

Any ideas what i could be missing?
