About Net Access Points

Net access points enable virtual machines (VMs) placed in a Net to access another OUTSCALE service using a private connection, which avoids using a VPN connection or a DirectLink connection.

For more information about OUTSCALE services, see About the APIs and OUTSCALE Object Storage (OOS).

Net access points enable you to create a private connection between your Net and another OUTSCALE service within the same Region as the Net. Using the Net access point, VMs in your Net communicate with resources of the other service using their private IPs. When using this solution, network traffic remains within 3DS OUTSCALE network.

When creating a Net access point, you specify the name of the service prefix list, which is a list of network prefixes used by this service in CIDR notation. Each prefix list is composed of an ID in the pl-xxxxxxxx format, and a name to identify the service it is associated with in the com.outscale.<REGION>.<SERVICE> format.

You also need to specify one or more route tables to associate with the Net access point, when creating it or once created. The appropriate routes are then automatically added to these route tables to route the traffic of their associated Subnets destined to the service to the Net access point. These routes have the corresponding prefix list ID as destination, representing the range of IPs used by the service, and the Net access point ID as target. All VMs placed in these Subnets therefore use the Net access point to access the service within the Net Region.

Net Access Point Architecture

  • If you do not specify any route table when creating the Net access point, you need to add them after creation to automatically create the appropriate routes in the specified route tables. For more information, see Adding or Removing a Route Table Associated with a Net Access Point.

  • As the most specific destination match is used to determine the route that applies, if the route tables contain a route directing all Internet traffic ( CIDR block) to an Internet gateway or a NAT service, the route using the Net access point takes precedence over the Internet one when directing traffic to the service within the Region. The Internet route is used for all other Internet traffic, including traffic to other 3DS OUTSCALE services or to traffic to this service in another Region.

The default security group for your Net allows all outbound traffic. If you created a custom security group or modified the outbound rule of the default security group, you need to add an outbound rule allowing traffic to the appropriate service. To do so, you can use its prefix list ID. For more information, see Adding Rules to a Security Group.

You cannot transfer a Net access point to another Net. You need to create a new one and, if needed delete the previous Net access point.

A Net access point can be in one of the following states:

  • Pending: The creation process is in progress.

  • Available: The Net access point is created and can be used to forward traffic to an OUTSCALE service.

  • Deleting: The deletion process is in progress.

  • Deleted: The Net access point is deleted.
