How to Set Firewall Rules on a GCP VM with Multiple NICs?

  • 772

GCP allows a VM to have multiple NICs, but firewall rules are governed by TAGS which unfortunately are attached at the VM level, NOT at the NIC level. So how would I configure totally different firewall rules on each NIC, given that tags only work on the VM level? Also in my case each NIC is in a separate VPC. Google's documentation is less than helpful.

    Google Cloud does not support attaching multiple NICs to the same VPC. Each Firewall rule is associated with one VPC.

    Create separate Firewall rules for each VPC.
