[ipv6] Odd behaviour...

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?
