Can anyone recommend an end-user IPv6 mailing list? (A web forum would also
be acceptable.)
I've been looking at available lists and they all seem targeted at backbone
players and ISPs. I'm looking for something where we can report and resolve
problems with our ISPs.
For example, I just got an AT&T business connection and the Edgemark fiber
gateway doesn't provide RA or prefix delegation. It assumes the customer
equipment is all leaf nodes that are statically-configured. It doesn't
recognize RA from the customer, either. So I'm using ndppd (added to EPEL7
this morning!) to proxy neighbor announcements through my CentOS7
gateway/firewall.
I have a backup/secondary C7 gateway and it got confused when the primary
sent RA for the LAN-side subnet upstream to the common WAN link (via the
radvd package) and the secondary added a default routing table entry
pointing to the primary gateway instead of using its own
statically-configured default gateway setting. That was a head-scratcher
until I noticed my firewall logs on the main gateway showing dropped DNS
packets from the secondary that should have been going to the ISP gateway.
IPv6 DNS was failing on the secondary with timeouts (10 seconds!) and I
couldn't figure out what was eating the packets.
So I'm wondering how multiple gateways sharing a link are supposed to
cooperate and inform each other without confusing each other about the
desired topology.
