Re: Dynamic IPv6

[mabi]

Hi Thomas,
Not using Cox here but in a similar setup here I use the dhcpcd package just 
for getting IPv6 from the ISP with SLAAC and prefix delegation. You will need 
to configure your /etc/dhcpcd.conf file to something looking like that:
noipv6rs
ipv6only
slaac private
nohook resolv.conf
interface em0
ipv6rs
iaid 1
ia_pd 2 em1/1
In that example em0 would be the WAN interface and em1 the LAN interface.
Good luck,
M.

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 working to configure a similar setup in OpenBSD 6.1 and I've been
unable to even get the outside interface to pull an IPv6 address from Cox.
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.
