Firewall

Restrictions

The firewall included with your dedicated server is a basic packet filter that only processes incoming packets. The following additional restrictions apply:

• Removing (not deactivating) ALL firewall rules results in the firewall itself being deactivated - no more filtering takes place (Any-Any Accept)!
• This also means: Adding a single rule always activates the firewall - only packets that have been explicitly enabled are allowed.
• A maximum of 20 rules can be created.
• We do not have any logs of rejected or accepted packets, so these cannot be used to assist with troubleshooting.

How to edit

To edit the firewall rules of your server, log in to CloudHub and open the dashboard of your server (Cloud Services -> Dedicated Server -> Select Server). At the bottom of the page you will find “Firewall configurations”.

The firewall rules are divided into IPv4/IPv6 rules (1). To edit the rules, switch to edit mode (2).

Editing and adding rules

If you want to add new firewall rules (1), please note the following:

• “Order” (2) affects the sorting of the firewall rules according to the numerical value. It is also possible to sort the existing rules using drag & drop.
• Source and destination ports (3, 4) are optional fields. If these are left empty, this corresponds to “any” or all ports.

The changes are then saved via “Save” & “Confirm changes”. It may take a few minutes for the changes to become active.
