BJ855-RIPE
Recently unable to setup tunnle after about 3 mounths of flawless service. Was working until 12-11-2008, Wireshark shows UDP packets sent to the pop but nothing ever comes back.
I know that this is behind NAT but Protocol 41 is forwared and has worked until now.
Tunnle: T13114
OS: WIndows 2003 Ent.
AICCU: aiccu-2008-03-15-windows-console.exe and aiccu-2006-07-23-windows-gui.exe
Iv tried include everything i can think of if you need anything elsa let me know. Also I have a 2nd tunnle on request so I could trouble shoot with it but still wating.
Thanks,
Brandon Jackson

Tunnel setup problem.
Note the !H for host unreachable on the ::1 address.
The "!H" is ambiguous as the version of this 'traceroute' tool is unknown and thus the exact meaning it has.
But looking at the PoP, it indicates that it doesn't receive proper heartbeat messages from your endpoint, and then indeed the PoP does not enable the <tunnel>::1 address as the tunnel is down.
You seem to have configured an MTU of 1472, is that really correct?
Another note is that AICCU states at the end:
"[error] Tunnel Setup Failed"
You have several places to look for errors for.

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:
Ok just like Nathan (Ticket 877659) for no reason its now back up and running with no chages didn't even restart aiccu. You sure no one did anything?
As for the MTU of 1472 its is correct 1480 being the Max for a ipv6 over ipv4 connection with a MTU of 1500 then minus the 8 for pppoe = a mtu of 1472 (1492 - 20 = 1472) and I setup Win 2003 for a MTU of 1472 on both interfaces (My "LAN" and "WAN") thus all ipv6 clients auto config for 1472 and it works fine.
Well since its working now ill let you know if it happens again.
p.s I shut down aiccu and did anouther "aiccu test" and again I got the same "[error] Tunnel Setup Failed" even though the the test setup the tunnle corectly and allowed for ipv6 connectivity, I even deleted the aiccu interface befor I ran the test to confirm and it went from no interface to a fully futional tunnle with the test still showing the same thing so not really sure whats up with it.
Thanks,

Ok I'm back to having the same problem again, My uschi02 tunnel (T13114) will not setup after being down for about 1hr with a new IP (Note: My Tunnel info page show the new ip from the heartbeat), I have connected to my new usdal01 tunnel (T18582) for the moment and it is working fine, any suggestions?
