Hello, I have Araknis AN-310-RT router behind the Internet Box. I can see that the Internet box receives ipv6 Delegated Prefix subnet 2001:1715:klmn:abcd::/60 subnet which seems to be publically routable. It also receives the CPE LAN IPv6 Address that is from this /60 subnet.
The Araknis router has Dual-Stack IP (IPv4 and IPv6) enabled and DHCP-PD enabled (I also tried manually using /64 from the initially given subnet). Hosts in the LAN network receive ipv6 from the Delegated Prefix (/60) but only can reach the Araknis router, not the Sunrise Internet Box.
Do you have any guidance on how can I use ipv6 over my router? Is there a way to configure DHCP-PD on the Internet Box?
