20.7 Legacy Series / Re: IPv6 DHCP gives IP to wrong VLAN ?
« on: May 03, 2020, 05:28:47 pm »OK, I choose Interface->WAN->Prefix delegation size "60" because I only need 5-6 subnet for me./60 on WAN is a reasonable choice.
When I change my setup and OPNSense is behind another router, I can´t get size "56".
Please say me, wich size I should choose.
Available prefix delegation size of 61 is fine, that's what we expect.
Available dhcp ranges is the same /60 in all cases. Thats bad.
I wonder how you managed getting a /60 on the LAN-side? It's supposed to be /64 for a single LAN-Net, i.e. Subnet mask 64 bits.

[LAN] -> IPv6 address xxx:xx:xxx:8b00:xxx:xxxx:fe92:8584 / 60Those should be /64 and everything is fine.

We need to get the 2001:db8:a:8b00::/60 into /64-Networks.
Did you try using different Prefix-IDs? Currently you're using 0x0 to 0x2 (or 0x6). Try setting LAN to prefix-ID 0x8, we expect the LAN to become 2001:db8:a:8b08::/64.
