How to customize your Cloud Server's Firewall

If you need your server's firewall rules to be different than the firewall rules configured by vpsmodel, you can customize your server's firewall.

Using a Firewall Management Service

The safest way to customize your firewall is to use a firewall management service, such as HeatShield, You can then log in to HeatShield to manage the firewall on all of your servers without needing to make any customizations from the command line.

HeatShield will not cause any conflicts with vpsmodel. Therefore, it is safe to use HeatShield on a server managed by vpsmodel.

Once you install HeatShield, vpsmodel will no longer attempt any firewall management on your server and will ignore any attempt to turn your firewall on or off in your server's Settings in vpsmodel. Instead, if you've installed HeatShield, you should log in to HeatShield to manage your server's firewall.

Manually Customizing Your Firewall

We can't provide support for problems due to incorrect firewall customizations.

You should only attempt manual firewall customization if you're an experienced sysadmin.

If you are experienced with server administration and firewall management, you can use any tool you prefer to manage your server's iptables firewall.

If you need to manually customize the firewall on your server, you should first disable vpsmodel's management of your server's firewall. To do this, log in to vpsmodel, go to your server's Settings, and choose the option to disable the firewall.

If you don't disable vpsmodel's management of your firewall, your customizations may be lost.
