Configuring Network Gateways

Learn about the different types of gateways you can configure on Compute Cloud@Customer.

This section describes the role and usage of each gateway type.

Network Address Translation (NAT) Gateways

A NAT gateway gives cloud resources without a public IP access to the on-premises network, which is an external public network from the point of view of a VCN, without exposing those resources. You create a NAT gateway in the context of a specific VCN, so the gateway is automatically attached to that VCN upon creation.

See NAT Gateways.

Internet Gateways

An internet gateway connects the edge of the VCN with the on-premises network. The ultimate target of the traffic routed through an internet gateway can be the internet.

See Internet Gateways.

Local Peering Gateways

VCN peering is the process of connecting multiple virtual cloud networks (VCNs) so that resources can communicate using private IP addresses. You can use VCN peering to divide your network into multiple VCNs, for example, based on departments or lines of business, with each VCN having direct private access to the others. You can also place shared resources into a single VCN that all the other VCNs can access privately.

See Local Peering Gateways (LPGs).

Dynamic Routing Gateways (DRGs)

a dynamic routing gateway, or DRG, provides a path for private network traffic between the VCN and an on-premises network. This traffic is routed to the data center network and on to its destination.

See Creating a Dynamic Routing Gateway.

Service Gateways

Service Gateway (SG). Some services are isolated on their own network for security and performance reasons. The service gateway (SG) allows a VCN with no external access to privately access Service Network services (such as object storage) in a private subnet.
