Hi,
After several long days of trying to figure this out
I must say I'm stumped.
I'm running OpenBSD 6.2 (GENERIC.MP) as of 9/26/17
AMD64 version with dhcpcd-6.11.5p4
Does anybody have a working IPv6 setup
that works with Comcast Business class service
that will allow me to use IPv6 on my LAN that
I could look at?
So far, all I can get to work is what I get
from placing "inet6 autoconf" in my WAN
and LAN interfaces.
I've now gotten rtadvd.conf to where i don't get errors
in /var/log/daemon.
I can ping from the command line of the router
any web address I enter.
I have dhcpcd-6.11.5p4 installed and have tried
countless variations of the readme file
example, the dist /etc/dhcpcd.conf, and various
other examples I've gotten from various places.
I've googled, searched mailing list archives,
and none of what I've found is helping me.
If ANYBODY has gotten this to work, could you
let me know what you did?
I'm just spinning my wheels, and I have RTFM
for days but just not fnding the answer.
Thanks, Ed

Hi,
I'm having trouble getting IPv6 working on
my router to assign IPv6 addresses to the computers
on my LAN.
I'm SURE there's something obvious I've been missing
and hope I can get a nudge back on track.
I have Comcast Business Class service, with a static
IPv6 address, 26xx:300f:1603:8000::/56
as well as a working block of IPv4 addresses.
I'm running OpenBSD 6.2 (GENERIC.MP) as of 9/26/17
AMD64 version.
I'm using em2 for my Internet facing interface
and em1 for my LAN facing interface.
By simply adding "inet6 autoconf" to
both hostname.em1 and hostname.em2, I get my IPv6 static IP
assigned to the router as shown below from ifconfig -A.
I and can ping6 any web address.
THE problem is taking the next step of getting IPv6
addresses assigned to computers on my LAN, which are
Windows 7 64bit Professional based systems.
In reading mailing list archives and te web, I see
dhcpcd being recommended to do this.
I've looked at the read-me file from the dhcpcd package,
the default /etc/dhcpcd.conf file, various posts
from email archives, and web posts.
I've experimented with them all in various configurations
and I get nothing that will simply add the capability
to assign IPv6 addresses to the computers on my LAN.
I also want to leave me present working IPv4 dhcp setup intact.
I would REALLY appreciate any direction with this, as there's
something I'm missing.
Thanks, Ed
I also get this in my daemon log
# cd /var/log
# cat daemon
