Introduction to public networks
Public Networks allow the users of virtual datacenters to use Internet addressable public IP addresses in their virtual infrastructure. **Users purchase or reserve public IPs for their enterprises in Virtual datacenters view. **Public networks are not assigned to any specific enterprise in Abiquo and they cannot be set as the default network for an enterprise. They can be set as the default network for a virtual datacenter, but make sure that you have made enough public IP addresses available to the users and that the users have reserved enough public IP addresses for their VMs.

Display public networks
To display public networks:
Go to Infrastructure → Private
Select a datacenter and go to Servers view
Go to Networks → Public
You can filter the list using the search boxes above the Networks list. You can scroll through the network list using the page number and arrow buttons at the bottom of the list. And you can search for text to filter the list by network names. 
...
On the right side of the screen, in the Public IPs pane, the platform displays the details of the IPs of the selected network.
To sort by a column, click in the header of the column.
To filter the results by any field, use the Search button.
To navigate through the pages, use the page scroll
...
Create public networks
Before you begin, obtain the network details from your Network Administrator
...
To create a public network do these steps:
Go to Infrastructure → Private
Select a datacenter and go to Servers → Networks → Public
At the bottom of the Networks list, click the + add button
For NSX-T, first select the Device
After you select the Device (nsxt-device), enter the Provider ID and select the Network service type.
Field | Value |
|---|---|
Name | The name of the public VLAN with up to 128 characters |
IPv6 | To create an IPv6 network, select this checkbox |
Strict | For IPv6 networks only. If you select Strict, the platform will automatically generate EUI64 IP addresses. |
Address | The network address of the VLAN |
Netmask | The network mask in CIDR format. For IPv4, the value can be from 16 to 30 inclusive, and for IPv6, enter a value of 64, 56, or 48 |
Gateway | The gateway of the network that must be within the range defined by the network address and the network mask |
Tag* | Enter the network tag (such as a VLAN or VXLAN tag) to use for this network |
Check | Click to check tag availability for all the racks of the Abiquo datacenter.
|
Network service type | Choose the Manage network service types, which assigns the network to network interfaces on the hypervisors |
Device | Optional device that defines a network virtualization system that will manage the IP addresses of this network. They may be assigned using its DHCP service. Ensure that VMs deployed on this network allow traffic to the appropriate ports for a DHCP connection. |
Primary DNS | Address of the primary DNS |
Secondary DNS | Address of the secondary DNS |
DNS suffix | The default DNS suffix |
Restricted | Select to create a Restricted network so that users require privileges to Attach NICs in restricted networks and/or Detach NICs from restricted networks |
Excluded from firewall | Select Excluded from firewall to define a network where VM firewalls will not apply |
Static routes | Click "Manage" to add and modify static routes. |
Provider ID | For NSX-T public networks, enter the path to the Tier 0 segment in the NSX-T system. |

Create IP addresses
Insert excerpt
On the Public IPs page, click the add + button and enter details
Or you can add an IP directly to a VM. To do this:
Go to Virtual datacenters → edit VM → Network
Click the add + button and enter details (or drag the Auto-generated IP label into the Network pane)
...
Enter the Number of IPs to create and the From IP address (the first in the range). The From IP address must be a new address that does not already exist in the network. After creating the first IP address, the platform will try to create the other IPs and it will skip any existing IP addresses.
For example, if you have IP addresses in network 30.30.30.30, which are 30, 33, and 34 and then you request 3 new IPs starting from 30.30.30.31. The new IPs created should be as follows: 31, 32, 35.
30.30.30.30 |
30.30.30.31 |
30.30.30.32 |
30.30.30.33 |
30.30.30.34 |
30.30.30.35 |
When you add IPv6 addresses on strict networks, you don't need to set the starting address. On non-strict IPv6 networks, we recommend that you create an automatic IP address, or you can enter a From IP address manually.
...
Set the default network for a virtual datacenter
...
To assign a network as the default for a virtual datacenter do these steps:
Go to myCloud Virtual datacenters
...
Select a virtual datacenter and go to Network
Select the network type, such as
PrivateCreate or edit a network
Select the Default network checkbox
This default will override the platform default network and any network set for the enterprise in the datacenter
The new default network will apply to all VMs deployed after you set it
For a public network that is the virtual datacenter default, obtain IP addresses for your VMs before you deploy
...
Edit a public network
To edit the Network Information for the public network
Go to Infrastructure → Private
Select a datacenter and go to
...
Network → Public
...
Edit the public network
...
When you edit a public network, you can change some or all of the following fields, depending on whether you have VMs deployed in the network or not.
Field | Description |
|---|---|
Name | The name of the public network |
Gateway | IPv4 only. The gateway of the network. The gateway must be an IP address inside the range defined by the network address and mask |
Tag | The tag to use for this network. Abiquo recommends that you check the tag for availability.
|
Network service type | Select the Network Service Type represents a network interface on the hypervisors. Configure the NIC in the switch and then configure the NSTs for your hosts. You cannot change the NST after users deploy VMs in the network |
Device | The device defines the network virtualization system to use for SDN |
Restricted | If selected, when users edit VMs, the only users who can work with IPs from this network are users with the privileges to Attach NICs in restricted networks and/or Detach NICs from restricted networks |
Static routes | Select Define to edit static routes for the network |
...
Before you begin, check that there are no enterprises that have purchased IP addresses from this network. You cannot delete a public network if any of its IP addresses are purchased, reserved, or in use. You cannot delete a public network that is the default for a virtual datacenter.
To delete a public network:
Go to Infrastructure →
...
Private
Select a datacenter and go to Network → Public
Select the public network
Click the delete button
...
Put an IP address on a deny list
...
To change quarantine status:
Select one or more IP addresses
Click the quarantine (
!) symbol and confirm
Selected IPs that were not in quarantine will be put into quarantine. Selected IPs that were already in quarantine will be removed from quarantine.
