Wondering if anyone has been able to get IPv6 working using an Asus router with Orcon UFB? I have had a trawl through the forums here but was unable to find any configs that people had working!

My router is an AX82U (running merlin 388.1 0-gnuton1).

Internet through IPv4 is working fantastically however I would like to try and get IPv6 working. Using connection type [Native] with DHCP-PD enabled and a prefix length of 56 my router is given an IPv6 address and by logging in through SSH I am able to ping IPv6 addresses no problem. Clients are given IPv6 addresses through DHCP (I get one on my laptop beginning fe80:, and two beginning 2404:) however they cannot ping or communicate with any IPv6 addresses.

An example traceroute6 from the router:

traceroute to google.com (2404:6800:4006:80b::200e), 30 hops max, 16 byte packets

and from my laptop

traceroute6 to google.com (2404:6800:4006:813::200e), 64 hops max, 12 byte packets

 2  default-rdns.vocus.co.nz  27.566 ms  27.344 ms  27.731 ms

Any idea what is going on? I tried searching online but couldn't quite find anything that would help, aside from suggestions that it was a routing issue?

Cheers!
