lamonthas anyone ran into the ipv6 stack _NOT_ accepting router advertisements despite being told to? (trusty with both 3.13.0-135 and 4.4.0-101)16:56
lamontapw: ^^16:56
apwlamont, i have not seen that, i am pretty sure i have a 4.4 but it might be out of date16:57
apwis this new behaviour16:57
lamontit's been something that I run into every reboot of this firewall, and then scratch my head for a few minutes, and manually add the router that I SEE ADVERTISING IN TCPDUMP, and then everything is fine unti lthe next reboot16:58
lamonttbf, it's eth0.55 that the RA is coming in on16:58
lamontand ip6tables are involved.16:58
lamonthttp://paste.ubuntu.com/26133655/ <-- trace of the packets coming in, INPUT:10 is an ACCEPT on router-advertisement16:59

lamontThe "all nodes" address ff02::1 is converted to 33:33:00:00:00:01. <-- I suspect that comcast is to blame.17:05
