Roteamento IPv6 // Destino inacessível: além do escopo do endereço de origem

Question

Eu quero configurar a Pilha dupla nas VMs do cliente. O roteador é uma VM também. Correndo no Debian Wheezy. Totalmente virtualizado pelo ESXi. O IPv4 está funcionando bem.

Ping da VM do cliente

ping6 -c 1 heise.de
PING heise.de(redirector.heise.de) 56 data bytes
From fe80::20c:29ff:fea2:cb92 icmp_seq=1 Destination unreachable: Beyond scope of source address

--- heise.de ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms

| cliente vm | --eth0 - > < --- eth1-- | roteamento vm | --eth0 - > (WAN)

Execute ping na VM do roteador

ping6 -c 1 XXXX: 4f8: 200: 640e :: 1 (XXXX: 4f8: 200: 640e :: também é bem sucedido)

PING XXXX:4f8:200:640e::1(XXXX:4f8:200:640e::1) 56 data bytes
64 bytes from XXXX:4f8:200:640e::1: icmp_seq=1 ttl=64 time=0.217 ms

Alguma ideia? Agradecemos antecipadamente.

Editar:

Existem 2 vSwitches

vSwitch0

Anexado ao nic físico. A VM do roteador está conectada a este vSwitch via eth0.

vSwitch1

Há todas as VMs do cliente e a VM do roteador (eth1) conectadas.
