Multiserver install: what did I do wrong and how is it supposed to work?

[Sinchan]

thanks for your reply Cssab, and about hostname, actually iam used computer name from Might and magic creatures games

and about uncomment bind_address at /etc/mysql/my.cnf, i had do that before and opened port mysql from the world, since i still didn't know how to filter mysql access at my.cnf bind address entry.

I tought i can use firewall filtering to do that, but if there are any other ways to filter mysql access with my.cnf rules, I would really appreciate it
