You can access block gateways through classic or VPC networks. To access block gateways, you must configure networks and security groups first.
- Access block gateways deployed on Alibaba Cloud
- To allow an ECS instance in a classic network to communicate with a block gateway deployed on Alibaba Cloud, you must use ClassicLink to connect the ECS instance to the block gateway first.
- To use an ECS instance deployed in a VPC network to access a block gateway deployed in another VPC network, use Express Connect or Cloud Enterprise Network.
- Access on-premises block gateways
To access a block gateway from an on-premises data center or private network where the gateway is deployed, configure your network based on the actual network conditions.
