TUN/TAP is a necessary function for LXC vServer, especially for users who want to operate a VPN. This is not possible by default with LXC. So that you as a customer can use your server in the best possible way, we automatically activate the adapter for you after the order. To use the adapter, it may be necessary to restart your server. The adapter is activated at the latest 5 minutes after the creation of your server. If you have ordered a fresh vServer from us and depend on the TUN/TAP adapter, you only have to wait 5 minutes and then restart your server. After that, you can simply use your server to its full extent.
