So correction again, I do have vlan10 assigned with an IP of 192.168.10.1/24, so that does appear correct.
I have enabled ipv6 on both the vlan and the main LAN. I get assigned leases on both with the correct prefix I have set, and I have a requested prefix delegation of /60 on the WAN side, which also appears to have applied correctly. LAN I can pass all ipv6 tests, but the vlan I’m never able to pass any of the devices.
