The CIDR block that can be used to mount the shares of a cloud gateway in V1.0.31 or earlier is determined by the CIDR block of the virtual private cloud (VPC) on which the gateway is created. The following table describes CIDR blocks that can be used to mount shares of gateways in V1.0.31 and earlier.
Gateway version | VPC CIDR block | VPC CIDR block supported for mounting |
V1.0.31 and earlier | 10.0.0.0/8 or its subnets | 10.0.0.0/8 |
192.168.0.0/16 or its subnets | 192.168.0.0/16 | |
172.16.0.0/12 or its subnets | 172.16.0.0/12 |
Starting from V1.0.32, a cloud gateway supports CIDR blocks of multiple VPCs. For more information, see Use CEN to connect ECS instances to a CSG instance and Use Express Connect to connect ECS instances to a CSG instance. The following table describes CIDR blocks that can be used to mount shares of gateways in V1.0.32 and later.
Gateway version | VPC CIDR block | VPC CIDR block supported for mounting |
V1.0.32 and later | 10.0.0.0/8 or its subnets | 10.0.0.0/8 172.16.0.0/12 |
192.168.0.0/16 or its subnets | 192.168.0.0/16 10.0.0.0/8 | |
172.16.0.0/12 or its subnets | 172.16.0.0/12 192.168.0.0/16 |

Standard VPC CIDR blocks include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
