Cox@home interconnection problems

[Ben et Nuts]

Do you guys know how I could Access other cox@home users' FTP or Exchange Files with them under MSN.
My friends are Cox@home users and they can't access my FTP, nor can I access theirs.

Thanks in advance

They have cut out the ports that do normal functions, ie 21 - FTP, 80 - http etc.

I have a lynksys 4 port gateway router and it show that I have a server of some sort. They cannot see any machine I have, not even my win2k server.
