Cant connect to FTP

I ran the microsoft network connection wizard because I want my internet connection to go directly to my computer
(that I have smartFTP on) and then share the connection (ICS) to my router.

Now it seems I can get on the internet ok, on the computer that has the direct connection, but I can't connect by FTP.

Continue to login attempt 6...
[16:00:00] Resolving host name ""

[16:00:21] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
[16:00:21] Cannot login waiting to retry (30s)...
[16:00:21] Client closed the connection.

Any idea hot that could happen?
