I have two servers behind the F5 having ports 4021 and 4022 configured for FTP.
VIP is configured with port 21.
When i am trying to get on to the servers (port 4022) directly using FTP credentials, i am able to login and retrieve the directory.
But when i go thorugh the F5, i am able to login but not able to retrieve the directory.
I have configured the FTP profile with Data port as 0.
I see an error saying "failed to retrieve directory listing" after i am logged into server.
Can anyone suggest me, what are the configurations that have to be done on F5 in this case.
