hi
i get hetzner server and installed proxmox 8.1,, i note that whatever the tutorial i follow to setup ipv6 as routed and use it on vms not workin even the stteps in hetzner site to install proxmox,,

i tried alot of methods only ipv4 work ,

any help for that ,,, i want only 3 vm which contains linux mint and connected by ipv6 only ??

i tried
https://community.hetzner.com/tutorials/install-and-configure-proxmox_ve

and
https://forum.proxmox.com/threads/proxmox-with-hetzner-what-a-love-story.127065/

and alot others, nothing work on proxmox 8.1
 
My only recommendation! Don't use Hetzner! lol hahahaha
Seriously! I can't help you on this! Have you contacted Hetzner support?
 
I think it related to proxmox ,, the ipv6 only work on the proxmox host server but i can't route it to any vm

Also, it work in version 7
 
i use all of the guides here

https://community.hetzner.com/tutorials/install-and-configure-proxmox_ve

and
https://forum.proxmox.com/threads/proxmox-with-hetzner-what-a-love-story.127065/

last current config as following

Code: 
auto lo
iface lo inet loopback

iface lo inet6 loopback

iface enp7s0 inet manual
auto vmbr0
iface vmbr0 inet static
        address 122.122.122.166/26
        bridge-ports enp7s0
        bridge-stp off
        bridge-fd 0
        gateway 122.122.122.100
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up echo 1 > /proc/sys/net/ipv4/conf/enp7s0/proxy_arp
post-up   iptables -t raw -I PREROUTING -i fwbr+ -j CT --zone 1
post-down iptables -t raw -D PREROUTING -i fwbr+ -j CT --zone 1


iface vmbr0 inet6 static
        address aaaa:aaaa:aaaa:aaaa::2/64
        gateway aaaa::1
up ip -6 route add aaaa:aaaa:aaaa:aaaa::/64 dev vmbr0
#up ip route add default via aaaa:aaaa:aaaa:aaaa::2

source /etc/network/interfaces.d/*

i enabled forward in the file /etc/sysctl.conf


ipv6 only work when i assign it to proxmox it self ,,
could you please guide me how to setup ipv6 correct way

You need the IP address (IPv4 or IPv6) on the vmbr0 to be correct, to access your host.
The hetzner method might be to migrate from a host with a native network adapter with given IP address to one with the address on the virtual bridge.
( I have IPaddress/24 (= actual netmask) for Ipv4 on the vmbr0 to access the host)
 
An external router handles routing between VLAN's using a 802.1q tagged vlan through eno0.
The VMBR's have interface as far as needed.
(There are a few more VLAN's for example to access a storage NAS, but it's configuration doesn't add to explaing the basics.)
The Storage LAN also has an IP address to allow for mounting iscsi devices on the procmox host.

Code: 
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
