We have observed on several occasion that RUTX09 drops its ipv6 route between device (::/0) and qmimux0. When that happens all ipv6 traffic in or out using the mobile connection is of course prevented. IPv4 routes are, however, unaltered and device's ip-address has not changed, at least not always, when it happens. Any idea what might be going on? We are using the latest firmware (RUTX_R_00.02.06).
