Configuring the Firewall on Private Cloud environments

The firewall is managed from the server’s Firewall menu.

Rules

Use this menu to find, create and adjust your firewall rules.

If you have a number of rules, the rule placed highest will take precedence over the others.

• API resource

Adding a rule

To add a rule, choose:

• the protocol: UDP or TCP
• the type of rule: ACCEPT, DROP (reject without informing the sender) or REJECT,
• the direction: in our out,
• the relevant IPs/hosts,
• the ports,
• The IPs version.

Not putting anything in Hosts and Ports will enable the rule for all unless a higher rule states the opposite.

It is possible to give a label by rules (Annotations) and directly in your rules by using the string #.

Firewall bans

Here you will see the IP addresses currently banned and the services that they are banned from.

If you end up banned from a service, check this menu and delete your IP if it is banned and add the necessary rule.

Services

This menu allows you to automatically open or close the ports for known functionalities (FTP, mail, SSH, databases, etc.). It is no longer necessary to create the rule manually.

Examples

Allow your own IP address to never be blocked on any ingoing port

Block the MySQL port from outside
