Problem with MySqlDataReader (no replies)

Hi all, i'm having a problem with MySqlDataReader and TimeOut.
The problem: i have to read a table in a remote database, the MySqlDataAdapter.ExecuteReader() returns in 2 seconds, ultra-fast. But when i put it in a DataTable throws an exception "IO TIMEOUT".
I test it puting in a DataSet, but the same problem.
(Note: over LAN there is no problem, via Internet is the problem)

Please help me.
Thanks!

Gonzalo.

Edit 2: I'm testing the application and Over Internet the datareader bring me 10969 records, after de timeout.
