You can setup ip filtering from your site manager. Just click on Site Management / IP Filtering. Enter an IP address of ‘*’ for Other and that will block to all ports EXCEPT 25 (SMTP), 110 (POP3), 80 (HTTP) and 21 (FTP). You would then have to create another rule to allow access from your IP to Other ports.

If you wanted to specifically block port 3306, then you might be able to add the file p3306 to /etc/hd/inf However, there is no guarantee that this would work as the ipf utility is a Westhost VPS special. These files have the format of one line per IP block, beginning with d for Deny or a for Allow. For example: d 10.0.0.1 a 127.0.0.1
