## Advanced options

### Change default FTP port

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range

By default FTP requests OS to give a free port automatically, however you may want to restrict
this to specific ports in certain restricted environments via

```
--ftp="passive-port-range=30000-40000"
```

### Change default SFTP port
