You'll also have to configure IPv6 RA and DHCPD. For IPv6, you'll need to configure a static IPv6 address (from your /64 range) on your internal LAN interface (via /etc/hostname.xxN) and add this to rc.conf.local: <code>rtadvd_flags=re1</code> (replace xxN with the name of your internal LAN interface, e.g re1). Configuring DHCPD is the same as Linux (ISC SANS DHCP server).

See the pppoe manpage for details, although with the realtek driver (reN), note that you may need to be running OpenBSD 5.8 for the right driver support.
