To allow remote access to MySQL, you have to comment out bind-address (you did) and skip-networking in the configuration file.
Next, you have to make sure the user is allowed remote access. Check your user with this:
SELECT User, Host FROM mysql.user;
If your user here has '127.0.0.1' or 'localhost' listed as host, you don't have remote access.
Change this with:
UPDATE mysql.user SET HOST='%' WHERE User='__here_your_username';
The '%' is a wildcard for 'all hosts'.
