CCC FTP command

Updated May 3, 2017

Overview

This article describes the use of the Clear Command Channel (CCC) FTP command.

Environment

All Serv-U versions

Detail

The CCC command is useful on client's requiring the usage of active (PORT) mode data transfers when they are behind a router that implements NAT. This command allows NAT to function on the router so that it can continue to "follow" the FTP transaction and alter the PORT command with an external IP address while preparing for the server's inbound connection on the port specified in that PORT command.
