Scope	FortiGate 120G.
Solution	By default the CAPWAP traffic is offloaded, when this is enabled the CAPWAP traffic is blocked. When running the debug flow, the following debug line could be seen, to confirm the session is installed in the NPU. id=65308 trace_id=2 func=ip_session_install_npu_session line=386 msg="npu session installation succeeded" The session is never established because FortiGate does not send the traffic, it is dropped instead. As a workaround, the following configuration could be applied. config system npu     set capwap-offload disable end The solution is to upgrade to v7.6.1.
