ftp-proxy enables you to use active mode FTP as a client behind a NAT
gateway. Active mode means the FTP server opens the data connection back
to the FTP client. Hence you need to let the data connection back in on
the external interface of the NAT gateway.
You probably also want to pass port 20 (or just about any connection)
out, if your NATed clients want to do passive mode FTP, where the client
connects to the server for the data connection as well.
