Windows 7 tunnel goes down unexpectedly
![[de]](/s/countries/de.gif) Shadow Hawkins on Tuesday, 08 December 2009 10:03:31
Dear all,
I have installed aiccu-console on Windows 7 and have done all the steps in the wiki for Vista configuration. In fact, the tunnel is running, but closed unexpectedly after different time. I have started the tunnel and it was still up after 5 minutes (heartbeat) but closed after 9 minutes. Stopped the tunnel and started it again it was up for 12 minutes. When trieing to ping I receive
C:\>ping -6 ipv6.google.com
Ping wird ausgefhrt fr ipv6.l.google.com [2001:4860:a003::68] mit 32 Bytes Dat
en:
Zielport nicht erreichbar.
Zielport nicht erreichbar.
Zielport nicht erreichbar.
Zielport nicht erreichbar.
Ping-Statistik fr 2001:4860:a003::68:
Pakete: Gesendet = 4, Empfangen = 0, Verloren = 4
(100% Verlust),
when the tunnel is down.
Can anybody help me please? I have no idea what to do. Do you need further information?
Thanks in advance
Sebastian

* Check the clock on your computer (NTP sync it with a local NTP server)
* Check your firewall, NAT box etc
=> Provide a LOT more information about your network.

Thanks for your reply!
Time is synced with 0.de.pool.ntp.org.
For testing reasons, I have switched off the firewall for the internal and external network in 7, but that does not help. I have a Mac within my network, and there are no problems running the tunnel over days. Thats why I think I have no problem with my fritzbox.
I have just this small aicco.conf:
username ****-SIXXS
password ********
tunnel_id T*****
verbose true
automatic false
What information do you need regarding my network? The 7 computer has a fixed ipv4 address (192.168.1.200) with fixed gateway and fixed DNS (the gatweway).
Installed is a Tun/Tap V9 as provided in the Wiki.
Is it normal that the Tun/Tap Network adapter semms not to be "cabled" after establishing the tunnel. It's still in state "Media disconnected".
The tunnel should be a 6in4 tunnel with is perfectly working on my Mac.
Any ideas?

Fritzboxes are effectively Linux boxes and they also do connection tracking, see the FAQ. But a better question is, why not terminate the tunnel on your fritzbox, quite a few models support IPv6 directly.

Tun/TAP is used for AYIYA tunnels, not for proto-41/6in4/heartbeat tunnels.

But not mine :-( (Fritzbox 7141)

Ok, i have just recognized that.
In fact the Fritzbox is also located in front of my Mac and my Mac is working properly. I'm really thinking that the problem is located in Win 7.
Is there anything I can check again?
Thank you very much!

Here is my output when starting the tunnel:
sock_getline() : "POP Id: dedus01"

This is what is confusing me
heartbeat_socket() - IPv4 : 192.168.1.200
Is this correct?

Of course that is correct, as that is your local tunnel endpoint.
One of the many things that can go wrong here is that your fritzbox sends return traffic (pop to you) to the wrong box, especially as you seem to have used both the mac and the windows box.
Hard to debug though. Wireshark might be one of the few things that can give you more information.
