WAN IPv6 Prefix Delegation doesn't work
I bought recently a new FVS328Gv2 as replacment for an older D-Link DIR-825. The FVS318Gv2 is connected to an AVM Fritz!Box 6490 which is the internet access router of my provider. The Fritz!Box 6490 allows to use a second router on its LAN side and offers an IPv6 subnet prefix via prefix delegation. This IPv6 prefix delegation has been working well with my DIR-825 so the Fritz!Box seams to be setup properly by me.
Let me now explain the steps taken with my new FVS328Gv2:
1. Unboxed the device and checked that it has FW Version 4.3.1-11
2. Upgraded to the latest version from netgear portal
3. Now the FVS328Gv2 is using FW Version 4.3.4-2
4. Setup IPv4 WAN via DHCP -> works fine
Fritz!Box 6490 delivers address, gateway and DNS to FVS328Gv2
Access to the internet is working and at good performance rate.
Fritz!Box 6490 has a static IPv4 route into my private LAN on FVS328Gv2.
5. Setup IPv6 WAN via DHCPv6 with IPv6 Prefix Delegation -> *** does not work ***
FVS328Gv2 gets an IPv6 address and gateway (the Fritz!Box 6490).
But WAN link status remains on 'connecting... ' and never ends.
Some time later it gets a primary DNS server (the Fritz!Box 6490).
But WAN link status remains on 'connecting... ' and never ends.
I never see a delegated prefix on the LAN configuration pages of the FVS328Gv2.
So I can't get IPv6 internet access from the LAN side of the FVS328Gv2.
The Fritz!Box does not offer static IPv6 routes so setup the FVS328Gv2 WAN manually will not work.
Note:
The Fritz!Box gets an IPv6 prefix of length 62 from my ISP. The former DIR-825 has been assigned properly a sub-prefix of the 63 by the Fritz!Box.
What am I doing wrong?
Hope for any help.
Thx Andreas

Hi AndiRauchhaus,
Welcome to the community! :)
Let me share the article below and it might help:
How to Configure Dynamic IPv6 Connection on a PROSAFE Firewall

NETGEAR Community TeamUps found I a typo in my post.
This post relates to the Netgear FVS318Gv2 not FVS328Gv2 as I wrote in the text.
Sorry for that.
Hi AndiRauchhaus,
Were you able to access the article I've shared? Hope it helped.

NETGEAR Community TeamYes I was able to access your document. And I tried to follow precisly the the steps descibed.
1. Frist I did a factory reset of my FVS318Gv2 to remove my old setup.
2. Tested the IPv6 connectivity directly when connected on my Fritzbox 6490.
Result was all Ok with a score of 10/10 point. So all is well on my Fritzbox side.
3. Activated IPv4/IPv6 mode on the FVS318Gv2.
Result was a reboot as expected. So this step was OK.
4. Selected DHVPv6 on WAN settings with stateless autoconfiguration and prefix delegation as described by the document.
I got the same result as descibed above in my post. The WAN connection stayed on 'connecting ...'
FVS318Gv2> show net wan wan ipv6 status Broadband

I don't know what's wrong. Try now to us the FVS318Gv2 in IPv4 mode only.
Are there any more experiences in connecting a FVS318Gv2 to a Fritzbox out there?
Here is my setup:
ISP <----> Fritzbox 6490 <----> FVS318Gv2
This line works fine on IPv4.
IPv6 is fine on the Fritzbox 6490 side but FVS318Gv2 does not get a IPv6 prefix delegation. Of course the Fritzbox 6490 is setup correctly as described by AVM to provide a second router. This worked well with my older DIR-825.
