How-to guides

Using core Virtual Private Cloud (VPC) functionality

• Using VPC networks

  Create networks and subnets, and modify existing ones.

• Using routes

  Create, modify, and work with network routes.

• Adding and removing network tags

  Add and remove instance tags used by firewall rules and routes.

• Using legacy networks

  Create and use legacy (non-VPC) networks.

Firewall

• Using VPC firewall rules

  Create and modify VPC firewall rules. Specify these rules at the network level.

• Using hierarchical firewall policies

  Create and modify hierarchical firewall policies. Specify these policy rules at the organization and folder levels.

• Using Firewall Rules Logging

  See which firewall rules affected your traffic.

VPC network sharing and peering

• Provisioning Shared VPC

  Set up a Shared VPC host project, assign service projects, and set up permissions for sharing a network with other projects.

• Deprovisioning Shared VPC

  Disassociate Shared VPC service projects from a host project. Disable a project as a host project.

• Using VPC Network Peering

  Configure two networks as peers or disconnect existing peers.

Configuring VM IP addresses and interfaces

• Reserving static internal IP addresses

  Reserve a static internal IP address. Assign a particular internal IP address to a Google Cloud resource. (Docs are hosted in the Compute Engine documentation.)

• Reserving static external IP addresses

  Reserve a static external IP address. Assign a particular external IP address to a Google Cloud resource. (Docs are hosted in the Compute Engine documentation.)

• Configuring alias IP ranges

  Assign a range of IP addresses to a Compute Engine virtual machine (VM) instance for use by containers or other services running on the VM.

• Creating instances with multiple network interfaces

  Configure a Compute Engine VM instance with more than one network interface so that it can be used as a virtual appliance that links VPC networks.

Packet Mirroring

• Using Packet Mirroring

  Configure a packet mirroring policy to specify mirrored sources and a collector destination.

• Monitoring Packet Mirroring

  View metrics for a packet mirroring policy to confirm that traffic is being properly mirrored.

Logging and monitoring

• Using VPC Flow Logs

  View traffic flow logs and metrics.

• Using Firewall Rules Logging

  See which firewall rules affected your traffic.

• Viewing VPC audit logs

  View audit logs for VPC resources.

• Using Serverless VPC Access audit logging

  View the audit logs created by Serverless VPC Access as part of Cloud Audit Logs.

Special configurations

• Configuring Private Google Access

  Allow VM instances in your VPC network subnet to reach Google APIs even if the VMs don't have external IP addresses.

• Configuring Private Google Access for on-premises hosts

  Enable your on-premises hosts to reach Google APIs and services through a Cloud VPN tunnel or Cloud Interconnect connection. Hosts don't need an external IP address.

• Configuring private services access

  Establish a private connection to services made available to your VPC network on internal IP addresses.

• Configuring Serverless VPC Access

  Connect from Cloud Run, Cloud Functions, and the App Engine standard environment directly to your VPC network.

• Configuring VMs for networking use cases

  Set up a Compute Engine VM instance as a network appliance.
