VCN connectivity can be achieved through gateways:
- Internet Gateway for egress to and ingress from the Internet to a public subnet
- NAT Gateway for egress to the Intermet from a private subnet
- Local Peering Gateway routes traffic between non-overlapping subnets in different VCNs in the same region.
- Dynamic Routing Gateway routes traffic between non-overlapping subnets in different VCNs in the same or different regions, or between customer premise equipment (CPE).
