Optimizing traffic routing operations in a two-box WLAN setup including a gateway device and a WAN adaptor device. The WAN adaptor device receives initial packets of a traffic flow from a client device, and sends the initial packets to the gateway device for slowpath (SP) processing. The gateway device creates fastpath (FP) processing rules for the traffic flow, including traffic modifications resulting from the SP processing, and sends the FP processing rules to the WAN adaptor device. The WAN adaptor device applies the FP processing rules to perform the traffic modifications on subsequent packets of the second traffic flow. The FP processing rules enable the WAN adaptor device to forward the subsequent packets of the traffic flow to the client device directly, without bridging to the gateway device for FP processing.
