Facing trouble while connecting GCP VPN from local computer


I am trying to connect GCP VPN from my local work station (windows 8.1).

On GCP, I have created Route Based VPN and VPN tunnel as google cloud's documentation. I have used IKEv2 on routing.

On my local computer I have created a VPN over IPSec using shared secret generated from GCP. Here is the screen shot of my local VPN settings:

VPN configuration

While connecting the vpn from my windows 8.1 pc, it shows the following error:

VPN error

and in the GCP side, VPN tunnel status shows:

IKE version mismatch

in the Cloud VPN Gateway log it shows:

establishing IKE_SA failed, peer not responding

It seems IKE version is not matching in both side. Am I missing anything that failed to match IKE version? or any way to enable 'IKEv2' on my windows pc? Any kind of suggestions are welcome.

Thanks in advance!


Solution

  • Cloud VPN is rather end-point to end-point; which may provide tunnels in between networks, with overlapping sub-nets. in order to connect with your client, you'd to setup an OpenVPN Access Server or alike, to provide the gateway which to connect.
