Hawk Host supports private / internal VLANs on compute plans in all locations. You will need to have at least 2 active compute services within the same data center to setup a private VLAN. Unfortunately it is not possible to provide a private VLAN that spans multiple data centers.
To have a private / internal VLAN configured on your computes please contact our support team at [email protected] or https://my.hawkhost.com/submitticket.php
