Typically, TUN/TAP is used when you want to utilize VPN services from your VPS.
We offer Windows VPS Hosting on Cloud and Microsoft HyperV based platforms. Our Windows VPS plans support TUN/TAP applications (VPN Services). Though we do not provide Windows VPS with pre-configured VPN services, you can install relevant software on your VPS and configure it at your end.
We offer Linux Classic VPS and Linux SSD VPS Hosting on SolusVM platform. In order to TUN/TAP to work on your Linux VPS, our Hypervisor / main host node will need to have the TUN/TAP kernel module installed and loaded. To have TUN/TAP in your SolusVM VPS, you can send us the request from client area, and we will enable it for you.
