How Abiquo implements classic firewalls

Abiquo implements vCloud firewall policies and classic firewalls at the Edge level, which is the distributed virtual firewall in vCenter and NSX.

First, when the user assigns a firewall to a deployed VM, the platform creates a new rule with the source or destination that points to the VM object.

Secondly, when a user creates a classic firewall rule, the platform will implement it as described in the following table.

When using a NAT IP in a VM, the platform also creates a firewall rule. And when using a public IP or NAT IP as a load balancer address, the platform also creates a firewall rule.

To restore the previous configuration with the firewall at the vApp network level, set the "abiquo.vcd.firewall.vappnetwork" property to true.

Onboard classic firewalls

Abiquo enables you to onboard and edit Classic firewalls from vCloud Director. A classic firewall is the firewall service in the orgVdc Edge. Users work with classic firewalls at the public cloud region level. In the platform there is no association between classic firewalls and virtual datacenters or classic firewalls and VMs. This means that when you onboard virtual resources, you must , so you may need to onboard classic firewalls in addition to virtual datacenters.

Change the sequence of rules in a classic firewall

In vCloud Director, when traffic arrives at the firewall, the Edge will attempt to match the rules from rule 0 to the end of the list of rules. The Edge will use the last rule (with the highest sequence number) as the default rule. The default rule must cover all ports from any source or destination and you cannot move an invalid rule into the last position.

The platform will maintain the rules in order with no gaps.

To change the order of rules, click the pencil edit button beside a sequence Sequence number, then enter a new sequence Sequence number and click "ok". The platform will move the other rules to fit around the changed rule.

For example, to move a rule from position 1 to position 2, enter 2 and click "ok".

Create and edit the rules of a classic firewall

...

You can edit existing rules and create new rules for classic firewalls. 

Warning
The last rule in the sequence is the default rule in the Edge. In vCloud Director, If you disable the default rule, in vCloud this will disable the firewall service in the Edge. This will mean that the rules will exist in the Edge but they will not be active.

To create a firewall rule, click the Add + add button and complete the following dialog. Include PageGUI Create classic firewall ruleGUI Create classic firewall rule
