Port 21 is only the "control" connection. There will also be a "data"  
connection which is on some other pair of ports coordinated between  
the client and server - this makes FTP a difficult protocol to handle  
through firewalls.

Does your router have any facility to act as a FTP proxy? Otherwise  
you're going to have to set up those dozens of forwarded ports so  
that the incoming FTP data connections will have somewhere to go.
