Google Cloud VPN IKE failures

Hi all,


I'm trying to create a VPN tunnel from an R80.40 Gateway to Google Cloud VPN, following the instructions from

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


What am I doing wrong?

Thanks in advance,


Bastiaan B.
