ftp to my xbox

I am new to my mac and I am having the hardest time connecting to my xbox through both yummy and fetch ftp software. I am connecting directly from the ethernet port on my mac to my xbox. the xbox deecs the connection and comes up static and some other things but I can not see it on my mac. It will connect and then atempt to get a file list and that is where it stops. I get the response cannot open data connection to 192.x.x.x i can not figure out how to get past this point. any help would be greatly appreciated. Thank you
