[AusNOG] Repeated NBN traffic flow issue

[Philip Loenneker]

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.
