Yea and the home routers rarely support ULAs. Hell, even UniFi which is supposed to be semi-pro: nothing, can't even disable DHCPv6 when you do DHCPv6 PD.
And then there is SRM on Synology... the amount of bugs I have reported on that is insane.
Which makes me think: is DNSMASQ the right tool for the job? It's extremely complicated in my opinion. If this, then that, but not when you do that thing over there.
UniFi technically supports it but you have to be willing to edit your gateway.config.json to do it, which is very error prone and super easy to screw up. So yeah, it’s still pretty awful. I switched to a plain OpenBSD box as my router because I hated UniFi’s IPv6 support so much.
