Eu tenho o seguinte problema.
Estou tentando configurar uma rede ipv6 em minha casa usando meu servidor com um túnel ipv6 como gateway.
Aqui está minha configuração
SERVIDOR :
interfaces do servidor:
he-ipv6 Link encap:IPv6-in-IPv4
inet6 addr: 2001:xxx:xx:xxx::x/64 Scope:Global
eth1 Link encap:Ethernet HWaddr 00:22:3f:f0:2a:a1
inet addr:172.16.1.1 Bcast:172.16.1.255 Mask:255.255.255.0
inet6 addr: 2002:c000:203::1/64 ##self assign ipv6 address for my home lan
tabela de roteamento ipv6:
ip -6 route
2001:470:6e:40f::1 dev he-ipv6 metric 1024
2002:xxxx:xxx::/64 dev eth1 proto kernel metric 256
default dev he-ipv6 metric 1024
tentativa de ping do google:
ping6 google.com
PING google.com(mil02s06-in-x00.1e100.net) 56 data bytes
64 bytes from mil02s06-in-x00.1e100.net: icmp_seq=1 ttl=56 time=103 ms
64 bytes from mil02s06-in-x00.1e100.net: icmp_seq=2 ttl=56 time=103 ms
--- google.com ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1000ms
Até aqui tudo bem
Cliente
interface do cliente:
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether d8:30:62:61:73:39
inet6 2002:c000:203::3 prefixlen 64
inet 172.16.1.134 net mask 0xffffff00 broadcast 172.16.1.255
tentativa do servidor de ping:
ping6 2002: c000: 203 :: 1
PING6 (56 = 40 + 8 + 8 bytes) 2002: c000: 203 :: 3 - > 2002: c000: 203 :: 1
16 bytes de 2002: c000: 203 :: 1, icmp_seq = 0 hlim = 64 tempo = 0,516 ms
tentativa de ping do google:
ping6 google.com
PING6(56=40+8+8 bytes) 2002:c000:203::3 --> 2a00:1450:400c:c09::66
--- google.com ping6 statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss
O mistério:
Quando estou fazendo um tcpdump no meu servidor enquanto estou pingando do meu cliente.
tcpdump -i eth1 -vv ip6
23:41:03.957019 IP6 (flowlabel 0x84719, hlim 64, next-header ICMPv6 (58) payload length: 16) 2002:c000:203::3 > mil01s18-in-x01.1e100.net: [icmp6 sum ok] ICMP6, echo request, seq 0

Qualquer ajuda?
