maybe someone knows how to approach this.
VPN server configured on windows server 2016
Clients can use pptp no problem.
I try to switch to L2TP but I can only connect from android phone (4g and wifi)
When I connect from windows 10 PRO ver 1909 "connecting" spins for minute or two and nothing happens. or I get error.
"How to troubleshoot a Microsoft L2TP/IPSec virtual private network client connection" at https://support.microsoft.com/en-us/help/325034/how-to-troubleshoot-a-microsoft-l2tp-ipsec-virtual-private-network-cli was not very useful.
Also I followed "L2TP/IPsec VPN On Windows Server 2016 Complete Lab (V2.0" https://gallery.technet.microsoft.com/L2TPIPsec-VPN-On-Windows-5cc2c3ae?redir=0
First I though this is server side error but if android phone can connect then how come windows pcs and iphone fail?
server: nothing l2tp related
I Am able to connect to vpn server from Windows 10 PC via LAN but still can't connect from internet see screenshot:
I would love to blame router but how come then I am able to connect from android via 4g?
