Hello All,
I have configured VPN on windows 2012 r2 server.
I am setting up a VPN to make use of machine cert so i make use of IKEv2 as VPN type on my client machine.
When i am trying to connect from my client machine i am seeing error 809.
I have already implemented the registry fix that MS recommend for this issue. I have already opened UDP port 4500, UDP port 500 and 1701 on client machine , my server which is acting as VPN server and my router machine, (I am using windows 7 machine as a router in which i have enabled ICS so that i can replicate the NAT scenario.)
Everything works fine when my machine get a real public ip. And everything works fine when i use user cert in nat scenario as well as the real public ip scenario
I have looked at the event viewer logs on my client machine and i see event id 20227 with the error code returned on failure is 809.
Can someone let me know as to how to troubleshoot this issue?
Thanks in Advance,
Ashish
