Google Cloud VPN IKE failures

[bastiaanb]

Hi all,

I'm trying to create a VPN tunnel from an R80.40 Gateway to Google Cloud VPN, following the instructions from https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut....

With IKEv1, the proposal from Google Cloud VPN is rejected:

Reject Category: IKE failure

Ike: Main Mode Failed to match proposal: Transform: AES-256, SHA1, Pre-shared secret, Group 2 (1024 bit); Reason: Wrong value for: Key Length

Same failure for both AES-128 and AES-256

With IKEv2, the proposal from Google Cloud VPN is dropped:

Reject Category: IKE failure

Encryption Failure: Ike version: ikev2 not supported for peer xxx.xxx.xxx.xxx

What am I doing wrong?

Thanks in advance,

Bastiaan B.
