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.
To display public networks:
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, you will see details of the IPs of the selected network. Click in the header of a column to sort by that column, use the Search button to filter the results by any field and navigate through the pages with the page scroll.
Before you begin:
To create a public network do these steps:
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.|
The network address of the VLAN
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
The gateway of the network that must be within the range defined by the network address and the network mask
Enter the VLAN or VXLAN tag to use for this network
Click to check tag availability for all the racks of the Abiquo datacenter.
|Network service type||Choose the Network Service Type, 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.|
Address of the primary DNS
Address of the secondary DNS
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|
Click "Manage" to add and modify static routes.
The platform will configure the static routes in VMs using the network configuration method. So it may not always be possible to update the static routes in a deployed VM. If you are using DHCP to configure VMs, changes to static routes will be received by the VMs when they reconnect to the DCHP server; for example, after they are restarted.
To add a Static Route:
Destination network mask
Destination network or host
Next hop (on your network)
The platform pre-creates the gateway address for IPv4 networks.
To add IP addresses to your network, click the + Add button in the top right-hand corner of the Networks page.
When you add IPv6 addresses on strict networks, you don't need to set the starting address.
On non-strict IPv6 networks, Abiquo recommends that you create an automatic IP address, or you can enter a From IP address manually as shown here.
After you create public, external, or NAT IP addresses, they will automatically be available to all users to purchase or reserve for their virtual datacenters. Abiquo recommends that you should make unavailable any IP addresses that will be used for administration purposes, for example, the IPv4 gateway network address. To edit the available IP addresses:
Abiquo recommends that you should make unavailable any IP addresses that will be used for administration purposes, for example, the IPv4 gateway network address.
To edit the available IP addresses:
To assign a public network as the default for a virtual datacenter do these steps:
To edit the Network Information for the public network, select it in the Networks list on the Public page. Then click the edit button above the Networks list.
When you edit a public network, you can change some or all of the following fields, depending on whether you have virtual machines deployed in the network or not.
The name of the public network
|Gateway||IPv4 only. The gateway of the network. Make sure the gateway is an IP address inside the range defined by the network address and the network mask|
The VLAN tag to use for this VLAN. Abiquo recommends that you check the tag for availability. Green: tag available. Yellow: tag already in use but can be shared. Red: tag excluded from use in the rack.
|Network service type||The Network Service Type, which represents a Network Interface on the hypervisors. Configure Network Service Types when you configure physical machines. Must be configured in the switch for use with VLANs. Cannot be changed when there are deployed VMs in the network|
|Device||The device pointing to the network virtualization system to use for SDN|
|Restricted||Mark this checkbox to restrict this network so that when editing VMs, only users with the privileges to Attach NICs in restricted networks and/or Detach NICs from restricted networks can work with IPs in these networks|
|Static routes||Select Define to edit static routes for the network|
You can modify these fields at any time but the changes will only apply to virtual machines deployed after the changes are made.
The address of the primary DNS server for your network
|Secondary DNS||The address of the secondary DNS server for your network|
The DNS suffix for your 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 or in use. To delete a public network, select it in the Networks list on the Public page and press the Delete buttonand the public network will be deleted.
Occasionally a user may misuse a Public IP and DNS providers may block it. Abiquo also enables you to quarantine IPs. This prevents another enterprise from reserving this IP and attaching it to another VM. Just select the problem IPs and click the Quarantine button on the top right-hand side of the IP list. This will toggle the current state of each IP address to or from quarantine. The following screenshot shows a network with two addresses selected. Clicking the ! button will put the first address into quarantine and remove the second address from quarantine.
