Configuring IPV6 - VM machine with internal ip and external IPV6

[Robson Rissato]

Hello friends, I am in need of help, to configure VM with IPV6, I have done almost everything but I am already lost in the settings, I will post as this is my current configuration.

if anyone can help.

# network interface settings

auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

auto vmbr0
iface vmbr0 inet static
address 145.26.25.49/32

auto vmbr1
iface vmbr1 inet static
address 192.168.1.1/24
bridge-ports none
bridge-stp off

post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '192.168.1.0/24' -o vmbr0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.1.0/24' -o vmbr0 -j MASQUERADE

# Ip above is just an example, real ips is ok with tests below
# ping 145.26.25.49 - ok xternal test
# ping 192.168.1.1 - ok xternal test
# ping6 2209:5100:130:b32::2 - ok external test

I created VM with ip 192.168.1.104

What I need to have ip 192.168.1.XXX and IPV6 on these VM's and ping internal and external access through ipv6 with external access for vms through ipv6.


does anyone know that he can be wrong in this configuration?

I believe that proxmox cannot work that way,
you will always need an ipv4 + ip6v to work

192.168.1.xxx + ipv6 does not work, I've tried everything ....
