debian12 under W10 host loses ipv6 connection after some seconds

Hello all,
I have the following configuration:

VirtualBox VM 7.0.14 r161095 win.amd64 (Jan 15 2024 14:59:30) release log
OS Product: Windows 10
OS Release: 10.0.19045

I created a debian12 box and want to use ipv6 .

I use a bridged network and use dhcp for ipv4 and ipv6. I also get a valid ipv6 address.

For some seconds after the start ipv6 runs fine and I can successfully ping -6 google

After a short time (which I am at the moment unable to specify) these ipv6 pings hang.

In my network i have several linux containers under proxmox which use the same dhcp server for ipv6 and these work fine. So I assume that the configuration of the dhcp server in itself is correct.

In my Windows host i can ping -6 as i please and it works.

Any ideas how to investigate further ?

Log is attached

Thanks a lot

Norbert
