Preventing WAN access to a Database

Question

How do I prevent WAN access to a particular database in SQLyog? I am able to grant full access to particular DB's, but not able to prevent them. I have a Web APP that runs on an internal server and accesses MySQL on the same server. I have created a SQL user with my workstations IP, but I am receiving access denied from dbconnect when I run the APP from my workstation.

Thanks,

Answer 1

MySQL does not allow connections from anything other than what you've specified. If you want to disallow access from a particular IP or network, then that mean that you've already gone and granted access to them.

1. Review the CREATE USER syntax, particularly the section on specifying hostnames.

2. Review the user accounts that you've already created:

   SELECT user, host, password FROM mysql.user;
   

   And then re-create them as necessary.

Other than than that, if you want to completely disallow WAN access then you should be looking at your firewall settings, not MySQL.
