May 30 2024

NAT Gateway
Supports the configuration of IP affinity to allow requests from the same private IP address to the same destination IP address to use the same elastic IP address (EIP) or NAT IP address.
Content

Intended customers: All NAT Gateway customers. Features released: Alibaba Cloud NAT Gateway has a new feature for configuring IP affinity. You can enable EIP affinity for an Internet NAT gateway or NAT IP affinity for a VPC NAT gateway to enforce that requests from the same private IP address to the same destination IP address always use the same egress IP address. Previously, requests from the same private IP address to the same destination might switch egress IP addresses. The new feature is ideal for scenarios that need a fixed egress IP address, such as API calls that depend on source IP address-based authentication or association of specific network policies.
