Hello Thomas,
if you're provider used dhcpv6 to announce you're ipv6 /64 to you then you can look at many Comcast provider openbsd howtos. I do the same with my Deutsche Telekom (vlan / pppoe / dhcpv6 for ipv6) setup and it works this way for me.

I've been searching for some time today to find information on how to configure this but there are many different "how tos" and not one of them has worked for me. Can anyone point me to some definitive documentation for configuring this in OpenBSD? Or advise as to how to set this up? Seems like it should be a pretty basic thing, but I just can't seem to get it right. I didn't post any sample configs as I've tried many (many) different ways to do this today and have removed all of those changes at this point.
