Unable to receive the file from FTP

[nasserho]

Hi, I set up an FTP server on my system. I ran into a problem, the clients are using the VBA code you put on the site to download the files. Customers who have Internet with valid IP can download files. Clients with dynamic IP are not able to download files I have sent you the FTP connection logs as an attachment. Please guide me how to solve this problem
