Rax20 and IPv6 from my ISP

[Retired_Member]

Hello!

As I can't add the model under the threads topic:

RAX20, Firmware Version V1.0.4.100_2.0.64

The problem is following: I tried to turn on ipv6 on auto detect and auto config, but neither option worked (4/20 on https://ipv6-test.com/). I did some Googleing and found the following info on my ISP-s help page (badly translated by me, i hope the terms are correct):

An IPv6 address is allocated to the Internet interface using the Prefix Delegation (PD) from the ISP network block 2001:7d0 /56.

When configuring IPv6, it is important to know that:

No IPv6 address is allocated to the WAN interface, a link-local address (unnumbered WAN) is used
IPv6 routing information comes through Routing Advertisment (RA) functionality
PD and DNS server addresses are sent via DHCPv6

So the question, is, what options do I have to pick and fill in the admin panel?

What modem/gateway is the router connected to?

None, I have an ONT in my apartment and a CAT6 cable from the ONT to the RAX, ipv6 worked with an older tplink and ddwrt, but rax20 cant seem to automatically work with it.

when you had the tp-link connected, were you able to check what the ipv6 settings were?
