Claim 3:
4. A gateway in a hybrid cloud environment, wherein the gateway is remotely connected to a first subnet of a first data center through a communication tunnel and is connected to a second subnet of a second data center, the first subnet and the second subnet have a same private network segment, the first data center is configured to provide a non-public cloud service, the second data center is configured to provide a public cloud service, and the gateway comprises a processor, a memory, and a communications interface, wherein the memory is configured to store computer-executable instructions, and when the gateway operates, the processor runs the computer-executable instructions in the memory to:
receive a first address resolution protocol ARP request packet sent by a first device in the first subnet, wherein the first ARP request packet is used to request a MAC address of a second device in the second subnet;
send a first ARP reply packet to the first device, wherein the first ARP reply packet carries a first MAC address of the gateway; and
obtain and record a first correspondence between a private network address of the second device and the MAC address of the second device in the second subnet.
