i have a Windows server 2016 installed in a Dell Machine. i Just use vpn with PPTP, but i need to change the security for L2TP... because is better for other devices clients like Ios and Android.
i have tried many tutorials on internet, but doenst work at all...
appearr some many errors, but the more usually is 789...
i have tried:
- put the server on DMZ
- open port 1701, 500, 4500 udp/TCP
- turn off the firewall of router and server
nothing Works for me!!!
my router : mitrastar GPT-2541GNAC-N1
i dont have other router and dont change that.
please Just bid If have the solution, i dont realise the money If you cant solved this.
- IF HAVE THE SOLUTION THE CLIENTS NEEDS CONTINUE WITH INTERNET ACCESS, PING THE SERVER AND ACCESS FILES BY SMB PROTOCOL WITH IP AND DNS NAME SERVER EXATCLY LIKE PPTP WORKS TODAY.
