Firewalls Management

cloud control firewalls

 

The Firewalls area is under the Security drop down menu in the Cloud Control Panel . Here you can view your currently configured and setup Firewall Profiles, as well as create new Firewall Profiles.

Firewall Profiles are firewall settings above the instance and allow for ease of firewall settings and configurations. You can apply them to one, many or even all of your  instances with Hostwinds.

Firewall Profiles provide a container for virtual firewall rules that control ingress (inbound to instances) and egress (outbound from instances) network traffic at the port level.

By default, they use a deny policy and only contain rules that allow specific traffic. Each port can reference one or more Firewall Profiles in an additive fashion. The firewall driver translates security group rules to a configuration for underlying packet filtering technology, such as iptables.

The listed Firewall Profiles will display the name of the group and a short description of the group.

To add rules, you’ll need to set the direction of the traffic the rule enforces, the protocol, IP type, Min and Max ports. Here’s a brief description of what each of these mean:

 

  • Direction: The direction of the traffic that the rule applies to, incoming will be traffic inbound to the instance, and outgoing will be traffic from the instance.
  • Protocol: Specifies the type of traffic, ICMP, TCP, UDP
  • IP Type: The IP type that the rule applies to: IPv4, or IPv6
  • Min Port: The minimum port that the rule applies to
  • Max Port: The maximum port that the rule applies to
