Supported Connection Profiles and Ports

Files.com supports both implicit and explicit mode FTP and FTPS. FTP uses well-known ports to infer the exact connection profile.

Command channel

• FTPS (implicit FTP over TLS) on ports 990 and 3990
• FTPeS (explicit FTP over TLS) on ports 21 and 3021
• Plain, insecure FTP on port 21 (disabled by default, but can be enabled if your business needs require it)

Data channel

• Passive (PASV) mode on port range 40000 to 50000

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.
