Global Internet Gateway Overview

After a global EIP is bound to an ECS, a global internet gateway is required to connect the VPC of the ECS to the global EIP so that the ECS can access the Internet through the global EIP. Before binding an ECS, you need to create a global internet gateway. Global internet gateways are free of charge.

When you bind a global internet gateway to a global EIP of an ECS, the system automatically lists the global internet gateway of the VPC that the ECS belongs to, if there is one.

  • If a global EIP is bound to a load balancer, you do not need to create a global internet gateway for the VPC that the load balancer belongs to.

Global Internet Gateway Quotas

Each VPC can only have one global internet gateway attached.

Notes and Constraints

After a global internet gateway is purchased, you cannot modify parameters such as subnet and more. If you want your global internet gateway to work in another subnet, delete it and create another global internet gateway.

What You Need to Do

Description

1

Creating a Global Internet Gateway

The global Internet gateway and the instance (for example, ECS) to be bound are in the same VPC.

2

Binding a Global Internet Gateway to a Global EIP

To enable an ECS to communicate with the Internet through a global EIP, you also need to bind a global internet gateway to the global EIP.
