IPv6-Adresse aus /64-Netz in Virtueller Maschine nutzen

Jimsem · Jul 19, 2016

Hallo zusammen,

ich schlage mich jetzt seit guten 2 Tagen mit der Einrichtung, einer IPv6 aus einem 64er-Netz rum, das bei meinem Dedicated-Rootserver von Webtropia inkl. ist.

Die Virtuelle Maschine Debian 8.5 ist auf einem Debian 8.5 Hostsystem mit virsh, qemu-kvm und virt-install installiert. IPv4 per NAT klappt, DHCP über dnsmasq alles super. Ich würde nur super gerne die IPv6-Adressen für die einzelnen VM nutzen.

Ich habe die 2001:4ba0:ffa4:36f::2 auf dem Hostsystem eingerichtet, das klappt auch ohne große Probleme, ich kann ping6 google.com machen und bekomme auch antworten.

Ich kann vom Host aus die IPv6 des Gastes pingen, ich kann mich sogar über die IPv6-Adresse der Bridge per SSH verbinden. Der Gast kann den Host über IPv6 nicht pingen.

Jetzt zu kommen wir wohl zu meinen Konfigurationen? Hier als erstes vom Host:

/etc/network/interfaces

Ich bin irgendwie etwas ratlos, ich habe schon verschiedene Tutorials durch, wie man das ganze auf einem Hetzner-Server zum laufen bekommt aber das klappt nicht. Ich habe auch schon ein super langes Ticket mit dem Support von Webtropia/myLoc, nur scheinen die auch nicht so Tief in dem Thema zu sein oder haben nicht richtig Zeit.

Ich hab auf dem Host auch mal ein tcpdump auf der virbr10 geamacht, dort kann ich die ausgehenden Requests sehen:

tcpdump -en -i virbr10 ip6 -vv

Ich habe sicherlich nur etwas vergessen, das Thema IPv6 ist etwas neu für mich aber ich möchte es gerne nutzen.

Du nutzt Bridged?

Ich bin mir nicht sicher, aber ich glaube, auf der VM solltest du nicht 2001:4ba0:ffa4:036f::3 als Gateway angeben. Das wäre ja dann Routed.

Hast du mal auf der VM das Gateway 2001:4ba0:ffa4:1:beef::1 eingetragen?

Ist es denkbar, dass ich der Bridge die selbe mac-adresse wie eth0 geben muss? Eigentlich nicht oder?

Ich habe das Netz jetzt einmal direkt über die virbr10 konfiguriert:

Code:

  address 2001:4ba0:ffa4:36f::1
  netmask 64

dazu noch folgende Routen hinzugefügt:

Code:

ip -6 ro add default via 2001:4ba0:ffa4:1:beef::1 dev virbr10

/etc/sysctl.conf

net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.all.proxy_ndp = 1

IPv6-Adresse aus /64-Netz in Virtueller Maschine nutzen
