Create a Firewall Rule


Create a Firewall Rule with a New IP Address Group

In the Firewall screen, each entry in the table represents a single firewall rule; however, each firewall rule can contain several IP addresses or just a single IP address. 

You can combine related IP addresses into a single IP Group. For example, if you want to block traffic from three separate IP address, you do not have to create three separate firewall rules. Instead, you can combine the three separate IP addresses into a single, configurable IP Group. Then, when you create a firewall rule, you can pick the newly created IP Group as your Source or Destination IP addresses.

 Step 1: Create an IP Group
  1. In the Armor Management Portal (AMP), on the left-side navigation, click Security

  2. Click Firewall

  3. If you have virtual machines in various data centers, then in the top drop-down menu, select the desired data center.  

  4. Click IP Groups
  5. Click Actions, and then click New Group
  6. In Name of IP Group, enter a descriptive name. 
  7. In IP Addresses, enter a member, and then click the plus icon.
    • You can enter:
      • A single IP address
      • A range of IP addresses
      • CIDR
    • You must add at least one member. 
    • You can add multiple members to a service group. 
  8. Click Create Group
    • The newly created IP group will appear at the bottom of the table. 
 Step 2: Create a Service Group

In the Firewall screen, each entry in the table represents a single firewall rule; however, each firewall rule can contain several protocols (and ports).

You can combine related protocols (and ports) into a Service Group. For example, if you want to create a firewall rule to block three types of traffic, you do not have to create three separate firewall rules. Instead, you can combine the three types of traffic (protocols and ports) into a single, configurable Service Group. Then, when you create a firewall rule, you can pick the newly created Service Group.

  1. In the Armor Management Portal (AMP), on the left-side navigation, click Security

  2. Click Firewall

  3. If you have virtual machines in various data centers, then in the top drop-down menu, select the desired data center.  

  4. Click Service Groups
  5. Click Actions, and then click New Group.  
  6. In Name of Service Group, enter a descriptive name. 
  7. In Services, enter the service or sub-protocol, and then click the plus ( + ) icon. 
    • You must add at least one member. 
    • You can add multiple members to a service group.
