Hi Ian - another Ian here.

First some empathy: I have use this sort of thing a few years ago when  
my daughter was in Japan for a year a few years back and found it a  
great way to keep in touch.

And now not to answer you question: If at all possible I would suggest  
that you consider using SFTP on a non-standard port and not FTP on  
port 21.  I think that you will get too many people knocking on your  
door so to speak.  By that I mean, people trying to break into your  

I allow SFTP into my home network (actually one of my Linux boxes) on  
a non-standard port instead of port 22 where one would normally expect  
to find SSH and SFTP.  It works a treat in a manner more or less what  
you are asking for.

Cheers, Ian Matters
