After new ECS instances are bought, default security group rules still exist. However, after the ECS server is synchronized with EDAS resources, five new rules are added to the ECS security group rules. The port number is "8182/8182", and the authorization objects are 10.152.0.0/16, 10.151.0.0/16, 10.143.0.0/16, 22.214.171.124/16, and 126.96.36.199/16.
- In the EDAS console, click Synchronize ECS.
- After ECS resources are successfully synchronized, you can view the new rules in the ECS security group rules.
