It found myself bursting into laugher reading Tim's replies (specifically the one including the phrase 'jammin on the jim jam frippen on the krotz') and decided right there and then that bugger it, I need to get to the bottom of the same problem that was happening here.</div><div class=""><br class=""></div><div class="">I had last week committed the cardinal sin of disabling v6 on my CPE (yes barely a router, <span style="font-family: Menlo-Regular;" class="">Jeroen) to get around exactly the same symptoms on my Masrhmallow device. So today I spent no less than six (6!) hours digging down to the bottom of it all using the combined knowledge I had gained, tcpdump, a whole bunch of RTFM and many many binary tests.</span></div><div class=""><span style="font-family: Menlo-Regular;" class=""><br class=""></span></div><div class=""><font face="Menlo-Regular" class="">To cut a long story short, my OpenWRT CPE was assigning it's LAN ULA v6 IP via RDNSS, but it wasn't responding to any DNS queries sent to that address. So DNS was borked for v6 queriers and the Marshmallow device wasn't elegantly routing around the damage like all the other hosts on my (W)LAN were. A similar run of events to those experienced by the ISP customers Eric reported.</font></div><div class=""><font face="Menlo-Regular" class=""><br class=""></font></div><div class=""><font face="Menlo-Regular" class="">The eventual work-around was to manually configure my ISP's (working :) v6 DNS resolver IPs into the odhcpd configuration.</font></div><div class=""><font face="Menlo-Regular" class=""><br class=""></font></div><div class=""><font face="Menlo-Regular" class="">So thanks everyone for your entertaining and informative discussions. Those, coupled with a 1/2 day of my time have provided the pleasant outcome of having v6 enabled again and all systems working :)</font></div><div class=""><font face="Menlo-Regular" class=""><br class=""></font></div><div class=""><font face="Menlo-Regular" class="">Pete Mundy</font></div><div class=""><font face="Menlo-Regular" class="">Nelson, New Zealand</font></div><div class=""><font face="Menlo-Regular" class=""><br class=""></font></div><div class=""><br class=""></div></body></html>
