I can confirm. Today at 13.54 I lost IPv6 connectivity through fihel01. My tunnel ID is T11473. PoP status on sixxs.net shows that the PoP is online. Running 'aiccu test' shows that I can ping the remote inner tunnel endpoint 2001:14b8:100:1ce::1, but beyond that everything else fails. The last part (traceroute6 to www.kame.net) shows the following: traceroute to www.kame.net (2001:200:dff:fff1:216:3eff:feb1:44d7), 30 hops max, 16 byte packets 1 gw-463.hel-01.fi.sixxs.net (2001:14b8:100:1ce::1) 15.156 ms 13.028 ms 17.157 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * 11 * * * 12 * * * 13 * * * 14 * * * 15 * * * 16 * * * 17 * * * 18 * * * By running 'ping' from an outside network to either my remote or local inner tunnel endpoint, we see the following: $ ping6 -c 3 2001:14b8:100:1ce::1 PING 2001:14b8:100:1ce::1(2001:14b8:100:1ce::1) 56 data bytes From 2001:14b8:0:3401::2 icmp_seq=2 Time exceeded: Hop limit From 2001:14b8:0:3401::2 icmp_seq=3 Time exceeded: Hop limit --- 2001:14b8:100:1ce::1 ping statistics --- 3 packets transmitted, 0 received, +2 errors, 100% packet loss, time 2009ms $ ping6 -c 3 2001:14b8:100:1ce::2 PING 2001:14b8:100:1ce::2(2001:14b8:100:1ce::2) 56 data bytes From 2001:14b8:0:3401::2 icmp_seq=2 Time exceeded: Hop limit From 2001:14b8:0:3401::2 icmp_seq=3 Time exceeded: Hop limit --- 2001:14b8:100:1ce::2 ping statistics --- 3 packets transmitted, 0 received, +2 errors, 100% packet loss, time 2009ms
