InternetGatewayBlockMode

The desired VPC Block Public Access mode for internet gateways in your account. We do not allow you to create this resource type in an "off" mode since off is the default value.

• block-bidirectional: Block all traffic to and from internet gateways and egress-only internet gateways in this Region (except for excluded VPCs and subnets).

• block-ingress: Block all internet traffic to the VPCs in this Region (except for VPCs or subnets which are excluded). Only traffic to and from NAT gateways and egress-only internet gateways is allowed because these gateways only allow outbound connections to be established.

Allowed values: block-bidirectional | block-ingress

Update requires: No interruption
