VPS SSD Firewall

The Firewall add-on service is based on the Linux software UFW. Its advantage over running this software on your own server is saving resources - traffic filtering takes place outside the server itself, thus saving its performance and connectivity.

Within this service, you can add up to 5×10 incoming and outgoing firewall rules.

Firewall activation

1. Log in to the customer administration ⧉.
2. In the navigation bar, select Server services VPS SSD.
3. Select the service from the list for which you want to activate Firewall.

6. In the add-on service detail, select the quantity (additional activations) and click the Activate button.

To change the number of activations or deactivate the service, follow the instructions in Services - Add-on services.
