For what it's worth, Comcrash assign me a /60 that I assign to my various interfaces as /64s, and they assign me a /128 as the global address via which all of the addresses in the /60 can be reached. Your ISP *should* do similarly.

Tehnically, I don't need a /64 on my external IF unless I intend to use NAT. In this case, 2**64 addresses should be enough for all of my inbound port forwards.

hi everyone
does the following error in//var/log//{messages,daemon} (openbsd) indicate a problem
at my internet providers end of the line or one of my config files

dhcpcd[82953]: pppoe0: DHCPv6 REPLY: NoAddrsAvail

Could be either end, but it's hard to check with the provider.


i have pd prefix addresses being assigned on my lan network but no nd
prefix address assigned to my egress interface on the firewall ?

dhcpcd.conf

ipv6only
noipv6rs
duid
persistent
option rapid_commit
require dhcp_server_identifier
slaac private
nohook resolv.conf, lookup-hostname
allowinterfaces em0 em1 tun0 pppoe0
script ""

interface pppoe0
   ia_na 1
   ia_pd 2 em0/0
   ia_pd 3 em1/1
   ia_pd 4 tun0/2

Are you sure you want to request 3 different prefixes? That might be the cause of the error.
Try this:
    ia_pd 2 em0/0 em1/1 tun0/2

hi Roy
i've modified the ia_pd line and all my internal interface have routeble addresses now,
my external interface still has no routeble address.
as far as i know  my config file are correct,
i have enabled default pass rules on any icpm6 passing through the firewall
and there are no blocks on udp ports 546 and 547 in the logs,
is there anything else i can try to narrow down the problem before i get on to my isp (zen internet uk).
i have included further logs below if they would help.
