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: * Always include clear descriptive information about your problem or inquiry. Some destinations that were previously reachable are now unreachable. The problem started some time this morning. * When on a UNIX-alike platform that supports AICCU, please run AICCU and run it using "aiccu test". * When using AICCU, check that you are using the latest version, and of course please specify where the binary comes from. The tunnel is up and works. My routes are set up correctly and not changed. * Always provide your NIC handle and if applicable the Tunnel or Route IDs you wish to discuss. JK22-SIXXS. This problem applies to other users and tunnels as well so not applicable. * Use the email address you have provided in your handle as that is what we use as a contact handle. * Provide details of the setup, type of connections, where NATs are located. I have a Linux router with a static tunnel to fihel01. No NATs are applicable. The connection is TeliaSonera Laajakaista Extra 24/2 Mbit/s, DHCP, bridged. * Provide information of your OS type, version and release (ie. uname -a), noting also the distribution name. joneskoo@hansu:~$ uname -a Linux hansu.m5.yx.fi 2.6.26 #1 SMP Thu Jul 17 17:25:25 EEST 2008 i686 GNU/Linux joneskoo@hansu:~$ cat /etc/debian_version 4.0 * Include full interface, routing and firewall tables. joneskoo@hansu:~$ ip link 1: lo: <LOOPBACK,UP,10000> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: tunl0: <NOARP> mtu 1480 qdisc noop link/ipip 0.0.0.0 brd 0.0.0.0 3: gre0: <NOARP> mtu 1476 qdisc noop link/gre 0.0.0.0 brd 0.0.0.0 4: sit0: <NOARP> mtu 1480 qdisc noop link/sit 0.0.0.0 brd 0.0.0.0 5: ip6tnl0: <NOARP> mtu 1460 qdisc noop link/tunnel6 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 brd 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 6: ge0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff 7: fe0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc htb qlen 1000 link/ether 00:13:d3:c8:25:c1 brd ff:ff:ff:ff:ff:ff 8: br0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff 9: vlan20@br0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff 10: brwan: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff 11: vlan10@br0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff 13: vlan100@br0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff 14: sixxs@NONE: <POINTOPOINT,NOARP,UP,10000> mtu 1480 qdisc noqueue link/sit 80.222.132.176 peer 62.78.96.38 20: vlan50@br0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:07:e9:0e:92:ce brd ff:ff:ff:ff:ff:ff joneskoo@hansu:~$ ip -6 route 2001:14b8:100:202::/64 via :: dev sixxs metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 2001:14b8:182::/64 dev vlan10 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 2001:14b8:182::/64 dev vlan10 metric 1024 mtu 1500 advmss 1440 hoplimit 4294967295 unreachable 2001:14b8:182::/48 dev lo metric 1024 error -101 mtu 16436 advmss 16376 hoplimit 4294967295 2002:d58b:a7dc:3::/64 dev vlan50 proto zebra metric 1 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev br0 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev ge0 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev vlan20 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev fe0 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev brwan metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev vlan10 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev vlan100 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 via :: dev sixxs metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 fe80::/64 dev vlan50 metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default dev sixxs metric 1024 mtu 1480 advmss 1420 hoplimit 4294967295 joneskoo@hansu:~$ sudo ip6tables -L -v -n Chain INPUT (policy ACCEPT 4173K packets, 417M bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 6086K packets, 4775M bytes) pkts bytes target prot opt in out source destination * Include a IPv4 and IPv6 traceroute to the PoP in question. traceroute to fihel01.sixxs.net (62.78.96.38), 30 hops max, 40 byte packets 1 dsl-olubrasgw1-fe40fb00-1.dhcp.inet.fi (84.251.64.1) 41.292 ms 4.777 ms 4.208 ms 2 141.208.151.153 (141.208.151.153) 4.252 ms 4.590 ms 3.910 ms 3 olucore1-e-0-1-0.datanet.tele.fi (141.208.12.145) 4.624 ms 4.668 ms 4.970 ms 4 hkicore1-e-1-1-0.datanet.tele.fi (141.208.8.1) 15.908 ms 15.971 ms 15.695 ms 5 hkiasbr1-s-0-0-0.datanet.tele.fi (141.208.8.10) 15.711 ms * 15.806 ms 6 dna.ficix1-ge.ficix.fi (193.110.226.20) 15.962 ms 16.372 ms 16.224 ms 7 van5r6.k.fv.fi (217.78.198.239) 16.560 ms 16.651 ms 16.739 ms 8 fihel01.sixxs.net (62.78.96.38) 16.495 ms 16.567 ms 16.734 ms traceroute to fihel01.sixxs.net (2001:14b8:0:3007::6) from 2001:14b8:100:202::2, 30 hops max, 16 byte packets 1 fihel01.sixxs.net (2001:14b8:0:3007::6) 17.198 ms 16.969 ms 16.801 ms * With heartbeat tunnels, first check clock synchronization or better: use AICCU. Static tunnel. * Check with Wireshark or tcpdumps of the interface over which the tunnel runs. Use -n (numeric) as an option and don't filter returning ICMP which could also come from routers between your endpoint and the PoP and also use -s 1500 so that one gets the full packet. * The status of the PoP is listed on the PoP Status page, if it is marked down there we are aware of the issue and we will try to resolve it as soon as possible. Additionally other issues are listed in the Ticket Tracker Ticket Tracker. * We are not your personal helpdesk, thus first read the FAQ and/or use the forum, many cases can already be solved that way, but we do want to have you actually use the tunnel thus do contact us if the problem persists. I don't think the forum is applicable in this scenario. ---------------------------- So here's the problem after the simple checklist.
