A method receives a request packet from a workload at a first logical interface of a logical router and determines that a source address is a first link local address for the workload and a destination address is a second link local address for the first logical interface. A second logical interface includes the second link local address. The method stores an identifier for the first logical interface as an egress interface. The identifier distinguishes the first logical interface from the second logical interface. A service is performed for the request packet and a response packet is generated. The response packet includes the source address of the second link local address for the first logical interface and the destination address of the first link local address for the workload. The method uses the identifier to select the first logical interface as the egress interface to send the response packet.
