[AusNOG] Repeated NBN traffic flow issue

[Patrick Ohearn]

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.
