My tunnel worked very fine about 40 days. Now it's working sometime and then stop working. I will paste some ping and tcpdump here:
only4fun ipv6 # tcpdump -i sixxs
tcpdump: WARNING: sixxs: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

0 May 13:24:58 ntpdate[25061]: adjust time server 130.233.224.2 offset -0.042518 sec
i haven't modified any config and have tryed this tunnel in 3 different computer's always same problem.
I don't know anymore what to do. If someone knows please help me ;)

Problem seems to be in heartbeat. Before it worked fine if
hb_sendinterval is 60
Now even i put it 15 I get's couple of "address unreachable"
Really don't what to do besides lower the hb_sendinterval value.
Connectivity problem
a) From the main forum page: Operational issues, abuse and other questions should be directed to the contact address.
b) Fix your clock and your connectivity.
Apparently you have a lot of packetloss in IPv4
Lowering the hb_sendinterval doesn't make sense unless you expect the connection to change every n seconds. The server will actually ignore anything that is less than 60 seconds. Thus it will cause a lot of useless traffic.

Don't know about packet loss. like i say 3 diffenrent computers and 3 different internet connection, every machine got synced time etc.. so how the problem can be
a) my ipv4 packet loss?
b) my clock?
And yes it really helped when changed the timeinterval to 15 sec. I know that because i change it back to 60sec and packet loss is then much higher.
And can't mail to info@sixxs.net because i have pete@only4fun.org in my 6bone handle and that computer has broken motherboard.

Do you have any NAT or connection tracking activated as this more looks like that packets going to your system get dropped:
18:08:38.447279 213.216.248.235 > 62.78.96.38: icmp: 213.216.248.235 protocol 41 unreachable
I suggest you fix your firewall and/or tunnel system and not do something foolish like the above. Heartbeats are only useful for notification of changing IP's and extending the lifetime of the tunnel configuration, they don't help with anything else. In your case though your NAT connection tracking might not loose the relation because it is updated every once in a while. Read the FAQ there is an entry there about that case.
You can't read your mail because there is only one computer handling it? :)
Never heared of a real mail setup (2x MX etc)... you also hopefully realize that you can't read your email and thus in the event that a notification has been sent to you about matters that you can't read it...
Connectivity problem
haha, I've found your problem.
You might want to run the heartbeat client from *1* PC and not two! ;)
Now that is REALLY stupid.
