• stopped (non-VDOM) deployment in obrienlabs.app
• review VDOM hidden status from Martin - https://community.fortinet.com/t5/FortiGate/Technical-Tip-HA-Reserved-Management-Interface-s-hidden-VDOM/ta-p/214783

  Requirements

  Adapt the 40net solution into the TEF (Bartek) https://github.com/40net-cloud/fortinet-gcp-solutions/tree/master/FortiGate https://github.com/fortinet/fortigate-terraform-deploy/tree/main/gcp/7.4 https://github.com/fortinet/fortigate-tutorial-gcp/tree/main/terraform last run from feb https://github.com/fortinet/fortigate-tutorial-gcp/issues/7

see example TEF deployment in #360 and https://github.com/GoogleCloudPlatform/pbmm-on-gcp-onboarding/issues/351

see alternate GCP native NGFW / Firewall+ overlay work in https://github.com/GoogleCloudPlatform/pbmm-on-gcp-onboarding/issues/396

• Ideally the NGFW work in 396 and 389 are pluggable and work as an option to the existing transitive VMs in the TEF
• see see https://github.com/hashicorp/terraform-provider-google/issues/17030 b/321386368

Discussion with Andrew - and a refresher. We are good with VM optimization down to e2-standard-4

As i understand it we need VM08 instances to get 4 nic's - I in my last couple deploys of the FG cluster did not vary with 04 or 02. Marian tested with 02 and as expected you can't customize up the nics - I would assume 08 VMs for now along with their up to $30 cost/day (excluding byol). Usually I keep the VMs off between debug sessions

checking my last deploy https://github.com/GoogleCloudPlatform/pubsec-declarative-toolkit/issues/446#issuecomment-1912757155 ...

yes

  machineType: n2-standard-4

yes, lets go with e2-standard-4 - as long as the VMs come up with all 4 nics - we are good

and my older tutorial run - I was mistaken - vm08 is the image not the vm size
