How to use the Cloud Firewall?

If you are not a fan of managing software firewalls within your Scalable Cloud Server, you can use our Cloud Firewall to allow and deny ports of your choice.

In this guide, we will show you how to allow port 22 for IP 10.10.1.254

Navigate to the Firewall tab on your Scalable Cloud Server

Select the Network Interface you need to set your Firewall rules for via the drop down menu

To view more details on your Network Interfaces, visit the Networking tab of your Scalable Cloud Server manage page.

Once selected, proceed to the next step to add firewall rules for the selected interface.

Click the collapse to add a new firewall rule

The following fields will appear to accept your new rule

Command: DROP or ACCEPT the rule, i.e., ACCEPT
Source IP: the source IPv4 or IPv6 address, i.e., 10.10.1.254

Protocole: TCP or UDP

Once the related fields are filled, proceed to add the rule by clicking the Add button

At this point, the rules are not applied to your Scalable Cloud Server, please feel free to add all the relevant rules before proceeding to the last step

Finally, once you have added all the rules, click on Apply Rules to save and activate the rules onto your Scalable Cloud Server
