Java Database Connectivity (JDBC)

Hi everybody...Well I have MySQL Server and Java, I get the JDBC and tried this:

###########################################################
import java.sql.*;

public class JdbcE {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql://localhost/test", "user", "pass");
if(!con.isClosed())
System.out.println("Successfully connected to MySQL server...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}
}
}
}
###########################################################

And with that code all works fine...but when I change the Host from LOCALHOST to [ROUTER IP] like this:

con = DriverManager.getConnection("jdbc:mysql://182.185.145.12/test", "user", "pass");

I got this exception:

###########################################################
Exception: Communications link failure due to underlying exception:

Last packet sent to the server was 16 ms ago.

I don't know how to solve it...
I have a 2wire 1700HG router, maybe it would be a problem of the firewall can anyone help me to solve this problem??
