Add Rule


A firewall needs a set of rules in order to do its job. Each rule tells the firewall what traffic to allow or deny, which VM to apply that rule to, which ports that traffic should be directed (or restricted from) on that VM, and which protocols to allow.When setting up rules, you will need to know IP addresses and Port Numbers for allowing and denying traffic. Any IP addresses for your VMs (Destinations) will be provided for you in the drop-down menu.

You can view a list of common port numbers in the Port Numbers topic.

 

 No more than 15 ports may be added to any firewall rule's destination or source list.

To add a new rule:

  1. Sign in to the Client Portal.
  2. Open the Manage mega menu.
  3. Click the  Virtual Firewalls link under the Public Cloud heading.
  4. Click Add Rule.

     Inactive rules are ignored by the firewall.
