Create a Linux share in Serv-U

I have Serv-U MFP installed on Windows. I have several network shares on a few Windows servers. In the Serv-U server, I have already added those shares to Serv-U by adding them as directories and I have created virtual paths. All of this works just fine with no issues.

Is there a way to provide the same type of access to files on a Linux server? I currently use WinSCP (on a Windows PC) to access files on the Linux server with a SFTP connection on port 22. My connection settings in WinSCP are:

...

Protocol: SFTP

Hostname: 192.168.1.210

Port: 22

Username: root

Password: ******
