Hi all, we have look in forum and found a howto to add ipv6 to proxmox.

we have do following:
Code: 
sysctl -w net.ipv6.conf.all.forwarding=1
than add ip:
Code: 
ip -6 ro add 2a02:238:f019:412::/64 dev vmbr0
than add gateway:
Code: 
ip -6 ro add default via 2a02:238:f019:401:2a0:57ff:fe14:86f5 dev vmbr0
than we have check it via ping6 to 2001:4860:4860::8888, and here we have not response:
Code: 
From fe80::21a:4bff:feaf:8cd2 icmp_seq=2 Destination unreachable: Address unreachable

what we can do here? do you have a idea, please?

route -6
Code:

what can we do here? hope for help. thanks and regards
 
You didnt add an ip, you added a route:

> ip -6 ro add 2a02:238:f019:412::/64 dev vmbr0

you never assigned an actual address to your interface, and you don't seem to have autoconf... you cant route traffic from the fe80 addresses as they're for link-local purposes only
 
Hi,

thanks for reply,

if i add as ipv6 [FONT=&amp]2a02:238:f019:412:1:1:1:1 i have the same issue.

how can i configure ipv6 on host with route or in /etc/network/interfaces

do you have more ideas?

ehm, if you add 2a02:238:f019:412:1:1:1:1/64 then you wont be able to reach your gateway of 2a02:238:f019:401:2a0:57ff:fe14:86f5 because its not in the same /64, you would need to add a gateway in 2a02:238:f019:401:*

try:

ip addr add 2a02:238:f019:401::1/64 dev vmbr0
ping6 2a02:238:f019:401:2a0:57ff:fe14:86f5

configuring it in debian is easy, in /etc/network/interfaces just add an iface vmbr0 inet6 block.. but test your config manually first

iface vmbr0 inet6 static
address 2a02:238:f019:412:1:1:1:1
netmask 64
gateway ????
 
hi bert64,

i have add following to the interface
Code: 
iface vmbr0 inet6 static
        address [COLOR=#1F497D]2a02:238:f019:412:1:1:1:1[/COLOR]
        netmask 64
        gateway [COLOR=#1F497D][FONT=&amp]2a02:238:f019:401:2a0:57ff:fe14:86f5[/FONT][/COLOR]

but if i restart network service its come:
Code: 
Reconfiguring network interfaces...
Waiting for vmbr0 to get ready (MAXWAIT is 2 seconds).
RTNETLINK answers: File exists
Failed to bring up vmbr0.
and i cant ping ....

do you have more ideas?

regards and thanks for your help...
 
yes that configuration will never work because the assigned address and gateway are in different /64 block

address is
2a02:238:f019:412::/64
gateway is 2a02:238:f019:401::/64

you either need to use a larger network size, or addresses in the same /64 range​
 
OK,

i have use /56 network
but after restart network service i get
Reconfiguring network interfaces...Device "vmbr0" does not exist.

and ping6 don´t work.

it´s the network still to small ?

regards
 
err, how is your gateway configured? both devices must be configured with the same network size
 
i have send a question to my provider, well i don´t have this information and for reply the correct information, if i receive it, i would post it. very thanks for help to here. i would post the answer of provider.

i have only my ipv6 network gateway adresse and the dns servers.

regards
 
hi bert64,

my provider said, we must set a route or use normal his gateway.
do you have a idea, to configure the ipv6 as working network?

i have following data:

ipv6-network: [FONT=&amp]2a02:238:f019:412::/64
ipv6-ip for my server: [/FONT][FONT=&amp]2a02:238:f019:412:1:1:1:1
gateway: [/FONT][FONT=&amp]fe80::2a0:57ff:fe14:86f5 or 2a02:238:f019:401:2a0:57ff:fe14:86f5[/FONT]
dns1: [FONT=&amp]2a02:238:f:11:0:2170:6922:4072
dns2: [/FONT][FONT=&amp]2001:4860:4860::8888 (Google)

i have test this
Code: 
[/FONT][/COLOR]iface vmbr0 inet6 static
        address 2a02:238:f019:412:1:1:1:1
        netmask 64
        up ip -6 route add default via 2a02:238:f019:401:2a0:57ff:fe14:86f5 dev vmbr0
        down ip -6 route del default via 2a02:238:f019:401:2a0:57ff:fe14:86f5 dev vmbr0[COLOR=#1F497D][FONT=&amp]

without result.

error message:
Code: 
[/FONT][/COLOR]/etc/init.d/networking restart
Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces ... (warning).
Reconfiguring network interfaces...
Waiting for vmbr0 to get ready (MAXWAIT is 2 seconds).
RTNETLINK answers: File exists

[COLOR=#1F497D][FONT=&amp]

i can ping my own ip but not the gateway andnot the google dns ipv6 adress.

do you or a other user have any ideas?

    gateway 2a02:238:f019:412:1:1:1:ff

same issue with
Code: 
...
iface vmbr0 inet6 static

         post-up ip -6 route add default via 2a02:238:f019:41FF:FF:FF:FF:FF # on active la passerelle comme route par default

...

but if i restart the network service i have the message:
