Private Network Overview

Private Network is layer 2 connectivity service which offers data center-wide connectivity between Leaseweb services.

Each customer who adds Private Network to their Leaseweb services automatically gets a single VLAN ID. Additionally we offer automated Private IP space assignment via DHCP to make it easier to use and avoid IP overlapping.
DHCP can be enabled or disabled from the Customer Portal.

Private Network connects Leaseweb services and products within a single data center or multiple data centers within a metro area. E.g. a Leaseweb service in AMS-02 can connect with a service in AMS-01. The services will be using the same transport VLAN ID and are in the same layer-2 domain.

Traffic generated between Leaseweb services using Private Network is not measured and is free of charge.

Multiple VLANs

Private network supports QinQ. QinQ (IEEE 802.1ad) is an Ethernet networking standard, which allows the private network traffic to be segmented with additional 4000 sub-VLAN’s within the single (1) Private Network VLAN that Leaseweb provides.

• It is enabled by default for all existing and new customers and is free of charge
• Customers have full control over the sub VLANs and IP subnet assignment
• Important The QinQ vlan’s traffic within the private network it’s not isolated just segmented.
• Existing Leaseweb products that support Multiple VLANs within the Private Network

How to set up and use Private Network for Dedicated Servers

Using the Leaseweb API or the Leaseweb Customer Portal, you can create a private network which connects two or more dedicated servers within the same data center or between interconnected data centers (in the same metro-area). For details, see the specifications below. Traffic sent between servers across the private network will not count towards your bandwidth costs.
For instructions, please refer to Private Network.

Different scenarios of using Private Network

This section describes possible scenarios using Private Network with Dedicated Servers (and Private Cloud).

Scenario	Graphical Representation
Database traffic and webserver application traffic is routed via the private network to ensure the traffic generated between the servers will be free of charge. Meanwhile all servers remain connected to the public network. Information It is important to configure your applications accordingly otherwise the traffic will still use the public network
In this setup, the public uplinks of the application and database servers are disabled from the Leaseweb Customer Portal (by disabling the public switch port). Both servers will not have internet access and will only serve their services using the internal network.
In this setup, all the servers are disconnected from their primary public uplinks. A server is installed as gateway. Such a scenario can be enlarged with software load balancers and firewalls. Information The public IPs of the different servers cannot be routed to this gateway box.
In this setup, Public Cloud Instances or Private Cloud VM’s are connected to Dedicated servers through Private network. Both virtual and Dedicated servers have their public uplinks active. This setup ensures that database or back up traffic generated between Dedicated servers and VM’s is unmetered and free of charge. Information It is important to configure your applications accordingly otherwise the traffic will still use the public network.
