When a new Elastic Compute Service (ECS) instance is purchased, a default security group rule is assigned. However, when the ECS instance is synchronized to Enterprise Distributed Application Service (EDAS), five ECS security group rules are added. The port number range is 8182/8182 and authorized CIDR blocks include 10.152.0.0/16, 10.151.0.0/16, 10.143.0.0/16, 11.193.0.0/16, and 11.192.0.0/16.
