Apparently, no gateway is being given out. But I am still trying to
clear that up. However ...

... I can ping now:
> ping6 ipv6.google.com
PING ipv6.google.com(iad04s01-in-x63.1e100.net) 56 data bytes
64 bytes from iad04s01-in-x63.1e100.net: icmp_seq=1 ttl=57 time=75.8 ms
64 bytes from iad04s01-in-x63.1e100.net: icmp_seq=2 ttl=57 time=74.8 ms
^C
--- ipv6.google.com ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1000ms
rtt min/avg/max/mdev = 74.870/75.380/75.890/0.510 ms
traceroute6 also work via all the IPv6 intermediate addresses.
What I have now is the following:
1)
Addresses given by my ISP:
HEX1::/64
HEX2::/56
2)
#for IPv6 config
iface eth0 inet6 static
address HEX1::01
netmask 64
network HEX1::
#for IPv6 config <--- this might be wrong though
iface eth1 inet6 static
address HEX2::01
netmask 64
network HEX2::
3)
I also have the "+ipv6" option in my dsl-provider file to be used when I
make an ADSL connection.
4)
And added the route:
$> sudo route --inet6 add default dev ppp0
So, looks like IPv6 is working on my router machine, and this by
assigning a fixed IPv6 address to my eth1 (from HEX1::64) and by
assigning HEX2::64 to eth0 (that connects to my LAN switch). But I
cannot yet ping6 from a LAN host.
Another question. I think I am not understanding the assignment of IPv6
subnets and addresses here. As in IPv4 we cannot have multiple nics in a
computer on the same network, is this the same in IPv6 as well?
Thanks.
