[AusNOG] Repeated NBN traffic flow issue

[Philip Loenneker]

Hi Russell,

We have checked that - no changes have been identified.

Unfortunately (but also fortunately!) none of the affected services are ones where we manage the CPE, so we have limited ability to troubleshoot by changing the configuration on them.

Hi Philip,
It might be worth checking in the service portal if there are any recent nbn changes against these services.

We have just had another 5 services reporting the same issue...

This is in Tasmania, covering many areas of the state.

Hi Patrick,

Thanks, I had forgotten about that! The CPE's in question range from Netgear to TP-Link to Mikrotik and others. We have seen it happen with Windows devices connected directly to the NTD.

Any idea if this issue ever becomes apparent after a firmware update of the NTD?

The 4 services that showed this issue since yesterday all started around the same time (2pm-ish), but some are over 200km apart.

Regards,
Philip

Hi Philip,

See Matt Carter's thread from Dec 2015 - http://lists.ausnog.net/pipermail/ausnog/2015-December/033838.html

This issue was resolved with NBN updating firmware on NTD'd early this year. I wonder if this bug has been re-introduced again in recent firmware updates.
