Step 1: Create an IP GroupIn 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. In the Armor Management Portal (AMP), on the left-side navigation, click Security. Click Firewall. If you have virtual machines in various data centers, then in the top drop-down menu, select the desired data center. - Click IP Groups.
- Click Actions, and then click New Group.
- In IP Group Name, enter a descriptive name.
- Armor recommends that you add Source or Destination into the name of the IP Group to help you identify the IP Group as the Source or Destination IP group.
- In Add Members To Group, 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.
- Click Apply.
- The newly created IP group will appear at the bottom of the table.
Step 2: Create a Service GroupIn 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. In the Armor Management Portal (AMP), on the left-side navigation, click Security. Click Firewall. If you have virtual machines in various data centers, then in the top drop-down menu, select the desired data center. - Click Service Groups.
- Click Actions, and then click New Group.
- In Service Group Name, enter a descriptive name.
- In Add Members To Group, 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.
Service or Sub-Protocol | Notes | Example |
---|
Services (TCP, UDP, etc.) | You must enter a port number. These services are not case-sensitive. | | Additional services (AARP, AH, etc.) | These additional services are not case-sensitive. Do not enter a port number with these additional services. | | Sub-protocols (echo-reply, redirect, etc.) | You must enter icmp, followed by the specific sub-protocol. You must enter the sub-protocol in lower-case letters. Do not enter a port number. | - icmp/source-host-isolated
- icmp/time-exceeded
|
- Click Apply.
- The newly created service group will appear at the bottom of the table.
Step 3: Create a Firewall Rule In the Armor Management Portal (AMP), on the left-side navigation, click Security. Click Firewall. If you have virtual machines in various data centers, then in the top menu, click the corresponding data center. Click Actions, and then click New Rule. - If you do not see Actions, then click Create a Firewall Rule.
- In Name, enter a descriptive name.
- In Action, select Allow to allow specified traffic to access your virtual machine or Block to block specified traffic.
- Under Service, enter and select the name of the desired Service Group.
- Under Source, enter and select the name of the desired IP Group.
- Under Destinations, in the field, enter and select the name of the desired IP Group.
- Click Save Rule.

After you create a rule, Armor recommends that you place the rule in the correct order. Reorder a rule: - Under Rule, in the numbered fields, enter a number to move the rule to a different position.
- If you have more than 25 rules, the additional rules will be placed in a secondary section within the Firewallscreen. To reorder and move these additional rules into a higher position, enter a number under the Ordercolumn, and then press Enter on your keyboard.
- In the top menu that appears, click Save.

If you are not familiar with ordering rules, contact Armor Support to help you properly order your firewall rules. It is extremely important to order rules in order to receive desired traffic. To learn how to send a support ticket, see Support Tickets. |
