Hello,
We currently have a setup of PPTP VPN + NPS on a Windows SBS 2008 server working just fine. Due to some plans of decommissioning the SBS in the future i am trying to configure the company's PPTP VPN on a secondary server running Windows server 2012 R2. I have installed both Remote Access and Routing Roles as well as the NPS role. I have copied the configuration i have on SBS to the new Server for both the PPTP VPN and the NPS. My issue is while i can connect to the new VPN using the server's local ip just fine when i use the server's public ip i get authentication failed. My firewall rules have been double checked and both 1723 and 47 ports are open. Can you please help me resolve this?
Thank you,
Kleanthis
