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.
Source or destination | New rule created using.... |
|---|---|
Any/Internal/External/All | A Network object. "Any" or "All" maps to ''VSE'' |
object:vcloudUrn Also ''IP Sets'' or ''Security Groups'', aggregations in NSX/vCloud, configured in orgVdc / Security | A VM (for example) object - (source or destination restricted to specific virtual machine) |
IP or IPstart-IPend or network CIDR | A single IP, a IP range or an IP network specification |
Comma separated list of the above values, e.g. 10.60.1.0,object:vmInternalProvidrId,10.60.2.0/24 | An IP, a VM, and a network CIDR |
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, so you may need to onboard classic firewalls separately.
To onboard classic firewalls:
Go to Virtual datacenters → Locations
Select a region
Go to Network → Classic firewalls
At the bottom of the Classic firewalls list, click the double-arrow synchronize button
For each classic firewall that you want to onboard, select the classic firewall and click the double-arrow synchronize button next to the firewall name. The platform will retrieve the classic firewall and its rules.
To synchronize a firewall that you onboarded earlier, click the synchronize double-arrow button beside the firewall name.
...
Troubleshooting: If the classic firewall tab does not display as expected, check that your platform has the correct UI configuration for this feature

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 number, then enter a new 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".
...
The platform will now move the rule that was in position 2 to position 1.
...
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, 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 button and complete the following dialog.
...
Field | Description |
|---|---|
Sequence | Position in the order of evaluation of rules, which is from lowest to highest with the default rule at the end. |
Protocols | Optionally select from the list of common protocols |
Source ports | The firewall rule will apply to this inclusive range of ports |
Source | Source can be in the following formats: IP address, CIDR, IP range, |
Destination ports | The firewall rule will apply to this inclusive range of ports |
Destination | Destination can be in the following formats: IP address, CIDR, IP range, |
Description | Describe the classic firewall rule |
Action | Select |
Logged | Select to use logging. Optional |
Enabled | Select to enable the rule. The last rule is the default. |
