In the displayed area, enter the IP address, subnet mask, and the default gateway address. Checking ECS Logs Check the ECS messages log in the /var/log/messages directory.
VPC Sharing Overview Edge gateway An edge gateway can connect subnets in the same VPC but from both edge and central AZs or from different edge AZs.
For example, in subnet 10.0.0.0/24, 10.0.0.1 is the gateway address, 10.0.0.253 is the system interface address, 10.0.0.254 is used by DHCP, and 10.0.0.255 is the broadcast address. The subnet CIDR block cannot be too large, either.
NOTE: When you add or modify a custom route in a default route table, the next hop type of the route cannot be set to VPN gateway, Direct Connect gateway, or Cloud connection. VPC peering connection Next Hop Mandatory Set the next hop.

This parameter cannot be set if the value of ip_version is 6. gateway_ip No String The gateway IP address cannot conflict with IP addresses configured for allocation_pools.
Virtual IP addresses Private IP addresses Used by the subnet itself, such as the gateway, DHCP, and system interface. Used by cloud resources, such as ECSs, RDS instances, and load balancers. Constraints A subnet cannot be deleted if its IP addresses are used by cloud resources.
In the Gateway and DNS Information area, view the DNS server addresses used by the ECS.
Use the gateway IP address of the subnet to create a router interface. port_id String No Specifies the port ID. Either subnet_id or port_id is used. Use the port IP address to create a router interface.
N/A Advanced Settings (Optional) > Gateway Click to expand the configuration area and set this parameter. The gateway address of the subnet.
This includes but is not limited to virtual networks, the OS of virtual machine hosts and guests, virtual firewalls, API Gateway, advanced security services, all types of cloud services, tenant data, identity accounts, and key management.
This parameter cannot be set if the value of ip_version is 6. gateway_ip String The gateway IP address cannot conflict with IP addresses configured for allocation_pools.

Advanced Settings (Optional) > Gateway 192.168.0.1 The gateway address of the subnet. You are advised to retain the default address. The gateway address cannot be changed after the subnet is created.
This parameter cannot be set if the value of ip_version is 6. gateway_ip String The gateway IP address cannot conflict with IP addresses configured for allocation_pools.
