When calling this interface, you need to pay attention to:

The parameter InnerAccessPolicy When the value is Accept, the networks between instances in the security group are interconnected. At this time, the Accept priority principle is followed, that is, the network between instances in the security group remains interconnected and is not affected by user-defined security group rules.

When the value of parameter InnerAccessPolicy is Drop, the network between instances in the security group is isolated. At this time, follow the priority principle of user-defined security group rules.
