Compatibility with FTP and FTPS

Because using FTP or FTPS (FTP over SSL) requires multiple dynamic ports for transferring data between server and client, ngrok is not a good solution for that traffic. We recommend using SFTP instead which relies on a single port number.

​
ngrok with SFTP

You can use ngrok for SFTP communication by opening up a TCP endpoint on the port used by the SFTP server, usually port 22 (the same as SSH). 
ngrok tcp 22
TCP endpoints are only available on a free plan after adding a valid payment method to your account.
From there, you can use the resulting TCP address in your preferred SFTP client to connect to your local server.

Alternatives to FTP for sharing files

If you’re just looking for a quick and easy way to serve local files, ngrok has a built in file server.
