FTPS on F5 LTM - HELP

Hi All We have managed to set up FTPS on our f5, we created a Virtual server on port 21 and also a Virtual server on all ports, this seemed to work. However when we try to do Active FTP it does not work. We followed the following article

Correct me if I am wrong but it looks like you need to set up 2 IP Forwarding virtual servers, one for all ports any protocol and the other for all ports TCP protocol.

 

We also changed the gateway of the server to point to the floating IP of the F5, does the F5 need any routes adding for this or will it just work as it knows which interface it came in on?

 

So in total, we now have 4 Virtual servers configured, FTP 21, One for all ports, then 2 IP forwarding Virtual servers, one for all ports and protocols and the other for all ports but TCP

 

Can anyone assist?
