Abstract
A network device in a distributed switch is provided. During operation, the network device receives information indicating allocation of a public Internet Protocol (IP) address and a subset of NAT ports available for a network address translation (NAT) instance deployed in the distributed switch. The network device maintains a first set of mappings of the public IP address and the subset of the NAT ports. The network device receives a packet destined to a public IP address and a first NAT port based on a forwarding rule. The network device replaces, using the NAT instance, the public IP address with a first private IP address of a user device and the first NAT port with a first protocol port in the packet based on a first mapping in the first set of mappings. The network device forwards the packet to the user device using the first private IP address.
