Minimum Gateway Instance Sizes for FireNet deployment

The minimum gateway instance sizes for Transit FireNet deployment (includes AWS TGW FireNet) are:

  • AWS: c5.xlarge

  • Azure: Standard_B2ms

  • GCP: n1-standard-1

  • OCI: VM.Standard2.4

These minimum instance sizes accommodate the interfaces (NICs for GCP) that are created when you attach firewalls to a Transit FireNet created in one of these cloud providers.

See Firewall Interface Specifications for information on what interfaces/NICs are created for each cloud provider/firewall.
