Odd behaviour...
Subsystems (2)
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:
(i renamed my host to piv6)
00:48:14.294173 IP6 piv6 > igloo.stacken.kth.se: ICMP6, echo request, seq 321, length 64
00:48:14.341288 IP6 igloo.stacken.kth.se > piv6: ICMP6, echo reply, seq 321, length 64
00:48:14.341317 IP6 fe80::55e4:1b90 > igloo.stacken.kth.se: ICMP6, redirect, piv6 to piv6, length 160
00:48:14.341332 IP6 igloo.stacken.kth.se > piv6: ICMP6, echo reply, seq 321, length 64
---
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?

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

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.

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.
