ipv4/ipv6 dual-stack configuration on OpenBSD6.0

[tech-lists]

Hello misc@,

I'm trying to find an *authoritative* walkthrough configuring an
OpenBSD-6.0 amd64 machine that currently runs fine as an ipv4 router for
my pppoe vdsl connection. The ipv4 network is a public /29. No NAT of
any description runs on this machine. There's two NICs, re0 which
connects to a vdsl modem and re1 which is the WAN and is directlt
connected to a switch, and pppoe0 controlling the connection.

I have a /64 for the WAN and a /48 for the LAN requesting ipv6
delegation. This is native IPv6. I think I'll need dhcpv6 to hand out
ipv6 addresses?

I'm looking for something like this:

https://www.openbsd.org/faq/faq6.html#Setup

but for ipv6 configs (ideally ipv4/6 dual stack). So far, searching has
turned up bits and pieces but some of it is old, there's differences
between versions, need something ideally specific to OpenBSD 6.0 so that
I'm confident it's setup right for this version.

any ideas?

thanks,

[Stuart Henderson]

On the gateway, pkg_add dhcpcd and see the pkg-readme. You'll most
likely want to hand addresses to clients via SLAAC (stateless address
autoconfiguration), this is done by running rtadvd on the gateway.
