Policy Based Routes. For ADCs that have dedicated management networks, we configure PBRs to make the NSIP a dedicated interface instead of just one of the data interfaces. Go to System > Network > PBRs and see if you have any configured. If your NSIP default gateway is different from your main appliance (data traffic) default gateway, then you need PBRs to steer NSIP-sourced traffic to the NSIP gateway/router.
