Hi,
I just recently acquired a new ipv6 tunnel since my two previous brokers
has gone out of business. I now use hurricane electrics tunnel since i
have really good ping times to it's node in Amsterdam.
Anyways, i have setup a local network tunnel and enabled forwarding.
After about 300 seconds, it all stops working. I have to disable and
re-enable it on the firewall/router to get it working again.
tcpdump shows the router/firewall doing odd things like:

fe80::55e4::1b90 is the local ip of the ipv6 tunnel.
(note: the packet never arrives at it's destination)
Any ideas of what could be going wrong?

What kernel version are you running?

Yeah. linux-net _might_ be a hive of activity, dunno. I haven't been
there in years. Perhaps it should be retired.

What kernel version are you running?
The router/fw is running 2.6.25.1, the client is running 2.6.25.4
Any additional information i should provide?
It would be interesting if you know of any earlier kernel version which
works OK?

Well, for me it was ages since i used ipv6... So i can't really help. I
was more hoping for someone in the same position or someone who'd seen
something simular and solved it.
From what i gather, i have done nothing wrong and a forward shouldn't
time out. Ie, if it works it should keep working.
It would be really interesting to see what the other end of a ipv6
tunnel sees when it pings, but i don't have the means to test that
currently.

How do you assign the address?
On the router/fw there is a sit tunnel thats started with 'ip'.
The clients get their addresses by radvd which only uses a local
interface on the router/fw...

It's very basic...
client -> router/fw -tap-tunnel-> -hurricane-electric-> internet.
(the firewall/router is my normal ipv4 firewall but for ipv6 it acts as
a router, thus the "router/fw" or "firewall/router".
but, router/fw -tap-tunnel-> -hurricane->electric-> internet. always
works, and outgoing communications always works. This is only a problem
for incoming communications.
