FTP Externally

I set up my FTP in MS IISv5. It works internally using “ftp locahost”. But I can not get it to work outside the home network. The website, also on IIS, is http://myname.me:1701. I tried for the ftp this ftp://myname.me and it did not work.
What am I doing wrong? What should IIS be setup for the default FTP to work? I can current get it to ask for login but it timesout after it does.
Thank you and God bless.
