I'm currently setting up one of the /48 networks from freenet6 and I'm having
some routing issues with my machines behind my tunnel endpoint.
The network looks like
192.168.10. network <-> my ipv6 gateway <-> freenet6 ipv6 gateway
I can do everything from my gateway and from the outside I can access all
the machines on my network with ipv6 addresses. The problem is that when
I try something like a ping from one of the internal machines I get
{26}: ping6 -n www.kame.net
PING www.kame.net(2001:200:0:4819:280:adff:fe71:81fc) from 3ffe:b80:411:1:250:4ff:fed6:1907 : 56 data bytes
From 3ffe:b80:411:1::1 icmp_seq=1 Destination unreachable: Address unreachable
From 3ffe:b80:411:1::1 icmp_seq=2 Destination unreachable: Address unreachable
--- www.kame.net ping statistics ---
2 packets transmitted, 0 received, +2 errors, 100% loss, time 1003ms
It actually worked at one point for a minute or two but I haven't been able
to get the behavior back again. I can ping all local ipv6 addresses on my
gateway from one of the 192.168.10 machines but get the error above trying
to ping anything beyond my machine. Seems like a route issue to me but I'm
not familiar enough with ipv6 to realize what route I'm missing. I've attached
the ifconfig and route info from my gateway below. I would have though the
::/0 route in there would have taken care of things.
thanks for any help
