Passive FTP is not working after installing CISCO Meraki firewall.

Hello,

 

We have integrated Cisco Meraki firewall newly in our environment and the traffic flow is like --- > users Outbound to ftp ---> cisco meraki ---- > link controller --- > internet.

 

We are trying to connect to a pasive FTP and we are getting connection timed out. When we bypass traffic back to CISCO ASA, ftp is working as expected. I would like to know if any one can suggest an ideal configuration between CISCO meraki and Link controller would be really helpful in this case.
