Example methods are provided a network device to perform service insertion in a public cloud environment that includes a first virtual network and a second virtual network. In one example method, in response to receiving a first encapsulated packet from a first virtualized computing instance located in the first virtual network, the network device may generate a decapsulated packet by performing decapsulation to remove, from the first encapsulated packet. The method may also comprise identifying a service path specified by a service insertion rule, and sending the decapsulated packet to the service path to cause the service path to process the decapsulated packet according to one or more services. The method may further comprise: in response to the network device receiving the decapsulated packet processed by the service path, sending the decapsulated packet, or generating and sending a second encapsulated packet, towards a destination address.
