FTP Connection fails

I have forwarded FTP on a predefined external port (42121), to port 21 internally. From outside network the connection gets established. It connects but it can’t complete the connection to list the folder and then drops due to time out. I heard that if the connection is established (FTP port 21 control port) the additional channels (ports) need by FTP to transfer data will be open dynamically. I believe Eero is not doing this. Any help on this?

    You'll want to use passive FTP instead of active - passive is able to traverse NAT since the client will initiate both the command and data connections to the server, instead of relying on the server to initiate the data connection which will be blocked by eero's firewall.

    Thanks for the info. But how we specify active passive when I am connecting to FTP server through windows explorer? I even tried from external website using coreftp with passive option and the FTP connection establishes. It is the data connection says time out to get the root directory. It says time out. I even increased the time, but no luck. I saw on internet and no perfect solution I found in regards to Eero devices.
