Disclosed are methods and apparatus for handling FTP (file transfer protocol) control packets. In general terms, mechanisms are provided for facilitating FTP sessions between devices utilizing different protocols, such as IPv4 and IPv6. For example, FTP control packets from an IPv6 client to an IPv4 server are handled to facilitate such communication.
