if you have a web proxy of some sort (like squid) you can set the
environment variables

ftp_proxy=ftp://youproxy.domain:port/
http_proxy=http://yourproxy.domain:port/

and ftp will use these.

see man ftp

ftp://[user:password@]host[:port]/file  An ftp URL, retrieved using the
                                             ftp protocol if ftp_proxy isn't
                                             defined.  Otherwise, transfer us-
                                             ing http via the proxy defined in
                                             ftp_proxy. If user:password@ is
                                             given and ftp_proxy isn't de-
                                             fined, login as user with a pass-
                                             word of password.

http://host[:port]/file     An http URL, retrieved using the
                                             http protocol.  If http_proxy is
                                             defined, it is used as a URL to
                                             an HTTP proxy server.
