• Traffic sent to an EC2 instance's public IPv4 or Elastic IP address has its destination translated by the internet gateway to the instance's private IPv4 address before delivery. in context
• An EC2 instance is only aware of its private VPC address; the internet gateway provides one-to-one NAT so outbound traffic carries the instance's public IPv4 or Elastic IP address. in context
• Because a cloud VM only sees its private address behind the provider's one-to-one NAT, a cloud-hosted SBC must be configured to write its public address into SIP and SDP, or remote peers receive unroutable private addresses. inferred in context
