FTP cant connect after setup ICS

I ran the microsoft network connection wizard because I want my internet
connection to go directly to my computer
(that I have FTP 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 "xxxxt.vwh.net"
[16:00:00] Connecting to 999.94.999.248 Port: 21
[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?
