Hello,
I have a problem with my IPv6 static Link to PoP deham01. My Name is Daniel Richardt(DRQ1-SIXXS). The Problem is at Tunnel T14524. My second Tunnel to deham01 from another Location runs properly.
Since yesterday (2009-06-25 16:42:04 CEST) no more traffic passing my Tunnel. Interesting because I changed nothing. In fact I was not at home and no other has access to the systems.
I've rebooted and checked every NAT and Firewall configuration on my site. All Traffic from deham01 to my IPv6 Gateway (Fedora) is routed properly and not firewalled. I've checked this with traceroutes and IPv4 connection from my Server which is hosted by my Provider.
In Detail my configuration :
deham01 -> IPv4 Internet -> Fritz!Box NAT -> pfsense Firewall -> Fedora IPv6 Gateway
Every connection from IPv4 Internet to the External IP of the Fritz!Box (static) is redirected (Exposed Host) to my IPv6 Gateway. At the moment the pfsense Firewall permitts any traffic from deham01 to my IPv6 Gateway. For test reasons I allowed any traffic to my IPv6 Gateway so I was able to connect to the Fedora Machine from any Internet PC (tested with SSH).
At the moment every of my tests points to an error at deham01. My pfsense Firewall Logs every Packet from my IPv6 Gateway and any incoming connection correctly. But there are seems no packets coming from deham01.
Also before the Problem the Loss Statistics logged about 400% packet loss but I think this is "impossible". Every connection worked fine in this time so i dont spend many time on this Statistics. Since the Problem the Packet Loss go back to 100% :) but nothing worked.
I hope you can help me!
Regards,
Daniel Richardt

Your log indicates that you DID change something, you disabled and the re-enabled the tunnel and then moved it to a IP address one below and then back again. (forgetting btw the fact that the PoP only gets synced every once in a while and not everytime you do something).
As you are behind at least one NAT and a firewall check that that those two keep correct state for the packets to go back and forth.
As you have a Fritz!Box there, why don't you actually terminate it there? It can do at least the tunnel perfectly fine (dunno about firewalling though). Would save the environment quite some power.

I have read and followed the "Reporting Problems" section on the Contact page and am providing the following details for this report based on the list of items stated there:
Hello Mr. Massar,
yes I changed some Tunnel Options AFTER the problem persists to try if some reconfiguration solves the problem (automatic reconfiguration or something like this). I dont know that the reconfiguration syncs only once in a while.
Point 2: I've checked the NAT and Firewall and i swear that the configuration is correct... (see Point 4)
Point 3: Sorry but i found no option in my "Fritz!Box Fon" to terminate the IPv6 traffic there. The IPv6 Gateway(Fedora) works fine and use no "real" more power because it's a virtual Machine at my FileServer.
Point 4....: I was now at work and again I changed nothing but everything works fine now (the Ping Stats say since 2009-06-26 22:00 -> I was at Work since 2009-06-26 18:00 till now (2009-06-27 01:00)).
My IPv6 Tunnel is now ok but the Packet Loss is back at 400%??? I will recheck this tomorrow but this make no sense for me...???
Thank you for your help!
Regards,
Daniel Richardt
