Can't ping tunnel endpoint anymore
Shadow Hawkins on Tuesday, 11 October 2011 08:46:58
Hi
Since yesterday night I'm not able to ping my POPs tunnel endpoint. I'm using a Fritz!Box 7390 to connect to SIXXS. No changes at my infrastructure were made.
Neither using the iPhone 4 (OS 4.3.3) nor Macbook Pro (Mac OS X 10.6.8) I can't connect to IPv6 addresses. Using the heise app on the iPhone - which seems to connect to the IPv6 address if IPv6 is enabled - I realized that the tunnel got a problem.
No firewall and no anti-virus software running.

Same for here with 2001:1620:f00:80::1
from any location from internet or local lan
They said the pop is up, nice, but the pop doesn't do any routing.
a ping6 nor a traceroute6 from external ipv6 internet hit the endpoint
And I lost -10 points with bot's email alert :-)

Please provide more running configuration details (interfaces, routing tables etc). That you can't reach anything remote primilary just indicates that the tunnel is not working.

As that is not the device terminating your tunnel, does that matter when the tunnel is broken?

Can't ping tunnel endpoint anymore
Jeroen Massar on Wednesday, 12 October 2011 15:15:32 And on the fritx.box (not using DSL anymore - for about two months - but a cable modem connected to LAN1):
Is that the device terminating the tunnel? As then I really wonder where the tunnel interface is.
34: dsl: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP200> mtu 1500 qlen 100 inet6 2001:1620:f00:90::2/64 scope global valid_lft forever preferred_lft forever [..]

That could be it, but it has an MTU of 1500 and further down in your paste it is noted as 'link/ppp'. SixXS does not do PPP, thus that cannot be it.
Also, those are RFC1918 addresses, what devices does your NAT so that this is supposed to work?
It would additionally be useful to see routing tables.

This ticket can be closed, problem solved (long ago)
