you probably need
a) the MySQL Dot Net Connector (ASP.Net machine)
b) this (below) in your Web Configuration File
<add name="MySqlConnectionString" connectionstring="server=tcp/ip address of MySQL DB Machine;User Id=Some User ID For DB;password=Password For User Account;database=Your Database Name">
providerName="MySql.Data.MySqlClient" /></add>
(this config data goes in a connectionstrings area in the web configuration file)
