I've being receiving the Tunnel Downtime mails for somedays now. My tunnel will be probably closed in a couple of days and I was the number one position of the Spanish uptime list (and one of the top ten in the global list). Why has this happen? NO fscking idea. I can ping my IPv4 and IPv6 end-points. I can ping kame.net. I can run all the aiccu tests successfully. I even brought my IPv6 firewall down (it had being running for more than a year without problems), but I still get the f***ing mails. I can't solve a problem I don't see. Can anyone give me any hints on this? TIA.
