localhost - Connect to Mysql from internet works, but when i try from mysql query browser it's failed (Err. 2003)

i can connect to mysql-phpmyadmin throught internet from browser(i.e google chrom),

but when i try it from mysql query browser it's always failed. It's always show error 2003.

i already created inbound rule to allow port 3306.
And installed ODBC Driver Connector ver 5.2.6.
I can connect to mysql from LAN, but somehow, i can not connect from Internet.
There is a different version mysql-phpmyadmin from LAN and Internet :

From LAN : MySQL

Server: localhost via TCP/IP

Server version: 5.5.16

From Internet

Database server

Server: Localhost via UNIX socket
Server type: MySQL
Server version: 5.1.73-cll - MySQL Community Server (GPLv2)

Is it the problem (The difference ver.) ? Should i install ODBC Connector ver 5.1.73 ? please help me to solve this problem

Thanks,
