But, I couldn't make it work because my upstream router would delegate the prefix, but not route the packets to my OpenBSD firewall. So, some form of NDP proxying is required. Nothing in the base or in the ports can do that, AFAIK. I ended up deploying a bridge. I also have the same issue, the prefix delegation from my ISP is dynamic, not static so, every time my router gets restarted, I get a new prefix from it. If your prefix delegation solution doesn't account for it, you might need some form of monitoring (ifstated comes to mind), to reload both your dhcp and rtadvd.
IIRC, OpenBSD isn't yet RFC 7084 ready (I have my doubts whether it even should be). One of the core things is, if the router lose global IPv6 connectivity, it MUST stop advertising itself as a IPv6 router. And rtadvd doesn't do that yet AFAIK. Truth is, most ISP's are ****ing up IPv6 deployment. Some of them are doing it for the money (charging more for something that should be default, as static PD). Others are doing it because of plain and simple lack of knowledge. Cheers, Giancarlo Razzolini
