Hi KayZerSoze,
>For example, to build a VPN Server allowing IKEv2/SSTP/L2TP, PPTP AND Direct Access at the same time?
Based on my understanding, you want to know if we can use one RRAS server to allow IKEv2/SSTP/L2TP, PPTP AND Direct Access at the same time. For example, computer1 use PPTP to connect to the RRAS sever, computer2 use L2TP to connect, computer3 use SSTP to
connect, etc.
If my understanding is correct, then it could, we may do that.
Here is a simple test environment with one computer use PPTP and another use L2TP:



However, when we deploy L2TP and SSTP, we need to ensure the related certificates are install correctly. If you meet specific issues when deploying L2TP and SSTP or DA, you may open case with the specific issue at that time. And NAP forum will be more suitable
