Client traffic was dropped by CAPWAP offloading when it connected from a mesh leaf Forti-AP managed by a FWF-61F local radio.

672920

CAPWAP tunnel traffic is dropped when offloading is enabled (with FAP managed by a VLAN interface). There are three workarounds:

  • Disable capwap-offload in system npu and reboot.

  • Set dtls-policy dtls enabled in wireless-controller wtp-profile. This may cause traffic to slow.

  • Enable UTM in the firewall policy (does not require reboot). This workaround cannot be applied on NP6Xlite FortiGates (FG-6xF and FG-10xF).

    config firewall policy
        edit <id>
            set utm-status enable
