Hey #illumos friends, I'm experimenting on a VPS. They assigned me a /64 IPv6 subnet, but I can't use it. Long story short, I think I need an NDP proxy, but as far as I know, one isn't available on illumos. So, I've created a ULA and mapped it using NAT66: map vioif0 myULA/64 -> publicIPV6/128. It works, but the server eventually crashes and reboots. When I look at the /var/adm/messages file, I see:

If I disable that map, it's stable (but I can't use ipV6 from the non global zones)

Any ideas?
