As Rick said, but additionally, as I indicated last evening, if you are 
going from work to your house, and your house has a firewall or router, 
then you need to set up port forwarding on your firewall or router to 
point the incoming port 21 traffic (if that's what you end up using) to 
the specific internal machine you want to talk to at home. You seem to 
have understood that in your original question, but I'm not sure any of 
us said exactly 'Yes', so I am. ;-)

Good luck,
