Any Luck with proxying FTPS or SFTP?

Has anyone had any luck with Proxying Secure FTP connections? Is this possible with the BigIP?     I currently have the latest and greatest 9.4.1 code with applied hotfix1.     -GW

Our back end servers were trying to establish outbound SFTP (FTP over SSL/TLS - not the sftp ssh subsystem) and the connections would hang trying to step up from FTP to SFTP.

 

 

We had to set up a wild card forwarding vip to get things working. I wasn't trying to accelerate anything - I was just trying to get SFTP working through the LTM.
