This guide describes how to use the Colocation Gateway service from the console.
To create a colocation gateway, use the following steps:
[Note] Only VPCs pre-registered in NHN Cloud Zone can communicate with the on-premises network. For VPCs that are required to communicate with the on-premises network, make sure that you contact through 1:1 inquiry of the NHN Cloud Customer Center before creating a colocation gateway.
[Caution] If you create a colocation gateway by selecting a VPC that is not pre-registered in the NHN Cloud Zone, communication with the on-premises network is not possible, and only communication with other VPCs connected to the same NHN Cloud Zone is available.
You can view the created colocation gateway on the Network > Colocation Gateway page. If you select a colocation gateway, the colocation gateway information appears at the bottom.
A colocation gateway can be modified as follows. You can only change Name and Description.
To delete a colocation gateway, select the colocation gateway you want to delete in the Network > Colocation Gateway page and click the Delete Colocation Gateway button.
Communication between VPCs connected to the same NHN Cloud Zone is routed by the NHN Cloud Zone by the longest prefix matching rule using the CIDR value configured in the VPC when creating a colocation gateway. When CIDRs are overlapped, only one random VPC among the overlapped targets is used for communication.
[Note] The TRANSIT_GATEWAY item can be created using Create Colocation Gateway.
