Public Networks allow the users of virtual datacenters to use Internet addressable public IP addresses in their virtual infrastructure. These networks are not assigned to any specific enterprise in Abiquo and they cannot be the default network for a virtual datacenter.
Public networks are managed from the Public page of the Datacenter Networks tab.
Click thebutton and complete the form.
Tag Availability Info*
The check availability button will check if the VLAN tag is available for all the racks of the datacenter. A public VLAN can be used on any rack and should be tagged in the same way on all racks. Tags in use by other VLANs will display a yellow warning signal but they may be used; only invalid tags will be rejected, with a red signal.
Abiquo allows you to configure Static Routes in the Abiquo DHCP Server when you create or edit a VLAN. Static Routes allow you to configure a path to a second network apart from the default route. For example, you can use them to allow access to both the corporate network and the Internet. Virtual machines will obtain their static routes from the DHCP server when they are deployed and started up. Changes to static routes will be received by the virtual machines when they reconnect to the DCHP server; for example, after they are restarted.
To add a Static Route, click the Manage button. The Static Routes dialog box will open. For each static route, enter its details. For example, to add a static route to the network/netmask 22.214.171.124/24 via the gateway/next hop 192.168.0.250, you would enter the details in the table below.
Abiquo will add the static routes to the DHCP server leases as option 249 for the Microsoft Classless Static Route Option and option 121 for the Classless Static Route Option in RFC3442.
For information on how to set up the DHCP server and clients (CentOS or Windows), see DHCP RFC3442 Classless Static Route Configuration.
To delete a static route, click the red delete buttonbeside the static route details.
For public networks, after you enter the Network Information, click Next to select available public IP addresses.
Leave the IPs you wish to offer to users in the left pane. The double arrow buttons will move all IPs to the other column. To move multiple IPs, select them and click the single arrow button.
You can assign a public network as the default for a virtual datacenter from the virtual datacenter's network screen. See virtual datacenter network management documentation.
To edit the Network Information for the public VLAN, select it in the VLAN list on the Public page. Then click thebutton in the right corner below the NETWORKS list and select 'Edit' from the menu. The form is the same as the Network Information form for creating a VLAN, but you can only change the VLAN name, VLAN tag, VLAN gateway and Network Service Type as long as there are no virtual machines deployed in the network.
To add or remove the Public IPs available for purchase, select the VLAN in the list, click the down arrow in theand select 'Edit IPs'. You will see the currently available and unavailable IPs.
Make your changes and click 'Accept'.
Purchased Public IPs and External IPs in use will not be shown
You cannot set to Not Available any public IP address that has been purchased by the users of an enterprise
Remember that IP addresses on the public network can be assigned to different enterprises.
To delete a VLAN, select it in the VLAN list on the Public page and press the Delete Buttonand the public VLAN will be deleted.
Restrictions on deleting VLANs
You cannot delete a public VLAN if users have purchased IP addresses in the network.
On the right side of the screen, in the PUBLIC IPs page, you will see details of the IPs of the selected public or external VLAN. 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. The VLAN type (Public VLAN or External VLAN) is shown in the bottom right section of the VLAN details when you click on the VLAN name.
Occasionally a user may misuse a Public IP. If this happens, the DNS providers can block this IP. Abiquo also allows you to mark an IP to quarantine it. This prevents another enterprise from reserving this IP and attaching it to another VM. Just select the problem IP and mark the quarantine checkbox. Then click Yes to confirm. The following screenshot shows a public network with the IP addresses in quarantine.
