Can I Specify the Backend Address as a Subnet IP Address?

If you use a dedicated gateway, you can specify either an IP address that belongs to the same subnet where the gateway is deployed, or the private address of a local data center connected to the gateway through Direct Connect.

Unsupported network segments:

  • 0.0.0.0/8
  • 10.0.0.0/8
  • 100.125.0.0/16
  • 127.0.0.0/8
  • 169.254.0.0/16
  • 172.16.0.0/12
  • 192.0.0.0/24
  • 192.0.2.0/24
  • 192.88.99.0/24
  • 192.168.0.0/16
  • 198.18.0.0/15
  • 198.51.100.0/24
  • 203.0.113.0/24
  • 224.0.0.0/4
  • 240.0.0.0/4
  • 255.255.255.255/32

If you use the shared gateway on the old console, you cannot specify the backend address as a subnet IP address. For a backend service deployed on multiple ECSs that are located in the same region but are not bound with any EIPs, create a VPC channel and associate the ECSs with it.
