Via an adjacent box (read second box on the same local network) he can
start an ssh tunnel to the remote host port forwarding port 24 which he
can in turn point g4u at....  It is a trick I have used myself :)  

sooo....

192.168.1.2 --ftp port 21-->> 192.168.1.3 --ssh-tunnel port forward port
21 -->> 10.0.0.2 port 21

You get a secure transfer without doing anything to g4u, you simply lie
to g4u :)
