Hi,

 

I'm trying to setup my ER605 behind a Fritz!Box 6660. IPv4 is working as expected. IPv6 is not - though I can see the Router Advertisements, nothing is happening in the ER605 (link down, no IP address on the status page).

 

I'm a novice regarding IPv6, though - and some details may not be compatible, so hands down on the configuration:

 

Network/IPv6/LAN:

 

Assigned Type: SLAAC+RDNSS

Prefix: Get from Prefix Delegation

IPv6 Prefix Delegation WAN: WAN/LAN1

IPv6 Prefix ID: 0

Address Prefix: (empty, read-only)

DNS Address : manual (cloudflare DNS)
Address: fe80...
 
Network/IPv6/WAN/LAN1:
 
IPv6 (/) ( 😄 )
Internet Connection Type: Dynamic IP (SLAAC/DHCPv6)
IPv6 Address: 2A02:.... (my prefix!)/64
DUID: (exists)
 
Advanced:
Get IPv6 Address: SLAAC+Stateless DHCP
Prefix Delegation: Enable
Prefix Delegation Size: 64
DNS Address: Use the following DNS Addresses (cloudflare)
 
Fritz!Box: disabled DHCPv6, enable SLAAC with M and O flag. As mentioned: Router Advertisement looks good to me.
 
I found this thread: https://community.tp-link.com/en/home/forum/topic/539038 which seems very similar at least, but unsolved.
