  • Dead Peer Detection Delay - 30 seconds

  • Encryption (Phase 1) - aes256

  • Encryption (Phase 2) - aes256

  • Integrity (Phase 1) - sha256

  • Integrity (Phase 2) - sha256

  • Diffie-Hellman Groups (Phase 1) - 16 - modp4096

You have now successfully connected your Google Cloud resources to GoodAccess.

Firewall rules

Make sure you allow connections from your GoodAccess Gateway private subnet to the resources in your VPC (e.g., virtual machines, databases, etc.).

Depending on your Google Cloud security setup, you may need to allow this communication in:

  • Cloud Firewall

  • Cloud NGFW

You may check the status of the connection in:

  • GoodAccess - Control Panel > Clouds & Branches > Edit button > Test connection

  • Google Cloud - Network Connectivity > VPN
