Problem with Crossover Cable

At my home, My modem is connected to Phone adaptor from Sunrocket.com
via crossover cable, From Adaptor,I have RJ-45 connectiong with my
Dlink Routher.

I used to have my frind log into my FTP machine. After new Phone
adaptor, I am giving my frined external IP address, however, he is not
been able to log into.

I used regular cable, however my friend is not able to connect to my
FTP machine.

Any thoughts?

thanks
Sam
