This guide describes how to use the Internet Gateway service from the console.
You can use an internet gateway by associating it with a routing table. When the internet gateway is associated with a routing table, it is assigned a public IP for internet access and adds the network configuration to the routing table with which it is associated. Association of internet gateway and routing table is provided in the VPC > Routing menu.
When the internet gateway is attached, a route entry for internet connection is added to the Route list in the routing table.
This route cannot be deleted manually. It is automatically deleted when the internet gateway is detached.
You can disassociate a routing table from an internet gateway. However, if there are instances or load balancers that associated floating IPs with subnets associated with the routing table, you can disassociate the routing table from the internet gateway after disassociating all the floating IPs. Disassociation of internet gateway and routing table is provided in the VPC > Routing menu.
When the internet gateway is detached, the route entry for internet connection is deleted from the Route list in the routing table.
An internet gateway can be deleted regardless of its status of association with a routing table. If you delete an internet gateway associated with a routing table, it is automatically disassociated from the routing table and then deleted. So, similar to "Detach an Internet Gateway", if there are instances or load balancers that associated floating IPs with subnets associated with the routing table, you can delete the internet gateway after disassociating all the floating IPs.
NHN Cloud updates software of the internet gateway server on a regular basis to enhance security and reliability of its infrastructure services. Internet gateways that are running on a maintenance target server must be restarted and migrated to the server where maintenance has been completed.
An internet gateway that requires a restart has a ! Restart button displayed next to its name. You can use this button to restart the gateway.
Go to the project where the internet gateway specified as a maintenance target is located, and perform a restart with the following steps.
The internet gateway becomes inoperable while it is being restarted. If the internet gateway is not restarted normally, the issue will be automatically reported to the administrator and NHN Cloud will contact you separately.
