Ipv6 not working for new VMS with proxmox 6.1

[munntj]

I recently switched to proxmox 6.1 with no openvswitch (just bridges). Things that used to have ipv6 addresses are fine, but new vms no longer are able to get slaac address assignments. It used to 'just work' and now everything I try fails. Any ideas?

no firewall used ? where is your router sending the router advertisement (RA) needed for slaac ?

#pve-version -v ?
