Is the NDP proxy for IPv6 supported on OmniOS?

not sure what an ndp proxy is, but autoconf works to me

Some providers don't allow routed traffic as they see it coming from different Mac addresses, so NDP proxy will proxy their traffic through the main interface's Mac address. It's useful for VMs or zones.

stefanobsdcafe: how does the main interface get's IPv6 if it cant be routed?

megaTherion: The main interface doesn't automatically get an IP. I configure it manually (from the details provided by the host provider). It's a /48.

For now, I solved using nat (1-1 - ULA for the zones and a 1-1 mapping on the global zone). On Hetzner I can just route and it is accepted but NetCUP and other providers seem to block this approach.
