Hello everyone I recently got IPv6 working at home LAN. My Android device (Google Nexus 5) is connected via wifi to LAN and LAN's core router is Map2N <http://routerboard.com/RBmAP2n>. I have a /64 on the LAN with "advertise" enabled to make ND to work and have autoconfig working on all devices. There are bunch of other layer 2 devices in LAN but all just acting as layer 2 transparently and core L3 remains on Map2N. All works well for most part but only trouble I am getting is on Nexus 5 where after around 24hrs IPv6 stops working. Only unusual thing I notice at that time is that phone 4 IPv6 as opposed to 2 (autoconf and temporary randomised address). Seems like some kind of issue in way NDP works either on Microtik or phone. The fix I am doing from few days is to restart wifi and phone interface gets fresh (two) IPv6 addresses and all works well again. Anyone facing similar issue? (Note: No issues on OS X or iOS which are in same LAN) I can try DHCPv6 but I guess most of devices do not support it yet. (I see support for that in routerboard though).
