I have an XE70 Pro Mesh setup and am attempting to use Verizon FiOS IPv6 service. This used to work fine on my older ASUS-WRT router as it had extensive IPv6 settings and better DDNS support for multiple/custom providers (such as Hurricane Electric tunnelbroker).

Whenever I pick Dynamic IP, enable Prefix delegation, and then for Assigned Type select SLAAC + Stateless DHCP, I properly receive a LAN address prefix, but the router itself does not receive an IP. I've also tried DHCPv6 as well as SLAAC + RDNSS but that also doesn't work. Tests on test-ipv6.com or ipv6-test.com also fail because I have no IPv6 address detected.

When I check my computers, I only see local IPv6 addresses being assigned.

These settings work on ASUS-WRT routers:

• Log in to your router dashboard and navigate to Advanced Settings > IPv6.
• Set the Connection Type to Native. FiOS uses DHCPv6, so setting it to Native with Prefix Delegation allows Verizon to assign you a dynamic IPv6 prefix.
• Ensure DHCP-PD is set to Enabled so your router can properly distribute IPv6 addresses to your local devices.
• Set Auto Configuration Setting to Stateless (or Auto depending on your specific firmware version).
• Set Enable Router Advertisement to Yes.

I think the problem is there's nowhere to Enable Router Advertisement on my Deco, and thats's why the connection is failing. I do get LAN prefixes assigned with the correct prefix, but the router itself is not getting its own IPv6 address, causing IPv6 traffic to not get forwarded onward.

I also tried setting up tunnelbroker to get an IPv6 connection this way, but there's a whole slew of missing settings there as well, plus I prefer not having a second ISP hop just to reach IPv6 addresses.
