Both active and passive mode FTP connections are supported.
In active mode, Files.com will attempt to connect back to the FTP client using the random data port that the FTP client specified. This requires you to configure inbound firewall rules from Files.com to your FTP client.
In passive (PASV) mode, your FTP client will attempt to connect to Files.com on a random port between 40000
and 50000
. This requires you to configure outbound firewall rules from your FTP client to Files.com.
