In my case I don't have a ppp interface, my CPE talks to my OpenBSD firewall through normal LAN. > DHCPv6 PD would give you a /64 or (if allowed by the ISP) a larger > prefix to assign to interfaces as you choose.

This is one of my problems, my ISP would only give me a /64 prefix, not a /56 or other manageable size. I can ask a PD from the CPE, but the only prefix already is delegated to the CPE itself. So the CPE keeps asking me neighbor solicitation messages, and won't route the packets. Unless I use NDP proxying, I can't do normal routing. As I stated, I did a bridge. When I have some free time I'll visit the NDP proxy again. Perhaps I'll be able to port some of the existing solutions to OpenBSD. Cheers, Giancarlo Razzolini
