OPNsense IPv6 Lan, Behind ISP Router Lan

[nfn]

Hi

I read some articles but I can't find a way to set IPv6 correctly with my ISP (MEO - Portugal)

My setup is: Internet <> ISP Router <> OPNsense <> Multiple VLans

This is what I have, just need some help to setup my OPnsense IPv6 lan:

Code Select Expand


ISP Router WAN:

IPv6 Address
2001:xxxx:xxxx:b000::1

IPv6 Prefix
2001:xxxx:xxxx:b000::/56

ISP Router LAN:

IPv6 Address
2001:xxxx:xxxx:b000::1

IPv6 Prefix
2001:xxxx:xxxx:b000::/64

IPv6 Link-local
fe80::xxxx:xxxx:fea5:daaf/64

OPNsense WAN:

IPv6 Address
2001:xxxx:xxxx:b000:6a1d:efff:fe36:20bf/64
fe80::xxxx:xxxx:fe36:20bf/64

Gateway
fe80::xxxx:xxxx:fea5:daaf

OPNsense LAN:

IPv6 Address
fe80::xxxx:xxxx:fe36:20c0/64


OPNsense WAN Interface:

IPv6 Configuration Type: DHCPV6
Request only an IPv6 prefix: Checked
Prefix delegation size: /64
Send IPv6 prefix hint: Checked

OPNsense LAN Interface:

IPv6 Configuration Type: Track interface
IPv6 Interface: WAN
IPv6 Prefix ID: 0x0

What should I do next to get IPv6 working correctly?

Thanks

Well, I don't know if it's possible to get IPv6 working with the previous setup, but I followed this article and it worked:

https://homenetworkguy.com/how-to/configure-ipv6-opnsense-with-isp-such-as-comcast-xfinity/

Relevant information if someone needs for this ISP:

ISP Router:

Must be set in Bridge Mode.

OPNsense WAN Interface:

IPv6 Configuration Type: DHCPV6
Request only an IPv6 prefix: Checked
Prefix delegation size: /56
Send IPv6 prefix hint: Checked

OPNsense LAN/VLAN Interface:

IPv6 Configuration Type: Track interface
IPv6 Interface: WAN
IPv6 Prefix ID: 0x1 - (*)

(*) I configured 0x1 for VLAN10, 0x2 for VLAN20 and so on!

Thanks
