Proxmox v5 IPV6

#1

Hello,

I’m trying to add IPv6 on my dedibox. I get a /56 and a /64.

Here is my configuration :

cat /etc/dhcp/dhclient6.conf
interface "vmbr0" {
   send dhcp6.client-id	<DUID>;
}
cat /etc/network/interfaces
auto lo
iface lo inet loopback

allow-hotplug enp0s20

iface enp0s20 inet manual

auto vmbr0
iface vmbr0 inet static
	address  163.172.24.XXX
	netmask  255.255.255.0
	gateway  163.172.24.1
	accept_ra 2
	bridge_ports enp0s20
	bridge_stp off
	bridge_fd 0

iface vmbr0 inet6 static
	address  2001:bc8:XXXX::1
	netmask  64
/etc/sysctl.conf
net.ipv6.conf.all.accept_ra = 2
net.ipv6.conf.default.proxy_ndp=1
net.ipv6.conf.all.proxy_ndp=1

When I run dhclient with this command, dhclient remove ipv6 address ???
dhclient -cf /etc/dhcp/dhclient6.conf -6 -P -v vmbr0

I seems I got a lease but I have to restart networking service in order to add IPv6 address on vmbr0. and then it works.

I opened a ticket but Online wasn’t able to help me.
