Ticket ID: SIXXS #673991 Ticket Status: User PoP: iedub01 - HEAnet (Dublin)
iedub01 appears to have lost tunnel routing information
![[ie]](/s/countries/ie.gif) Shadow Hawkins on Tuesday, 19 February 2008 14:06:03
Static tunnel on OpenBSD 4.1 was working correctly until some time on Sunday at which time iedub01 stopped responding to pings. I have since recieved two tunnel notifications.
Tunnel ID is T2629, name cobbled.net
Subnet ID is R1299
Yesterday (2008-02-19) all pings to and from the gateway and POP failed although it appeared that some TCP traffic was, erratically getting through, although I cannot be sure that applications were not falling back to IPv4.
Both tunnel and subnets appear to be enabled on sixxs.net home page.

I can ping the PoP's endpoint fine:
64 bytes from 2001:770:100:21::1: icmp_seq=1 ttl=55 time=30.8 ms
and also your tunnel endpoint:
64 bytes from 2001:770:100:21::2: icmp_seq=1 ttl=64 time=11.4 ms
Where does this go wrong?

i can only guess that there is some erratic problem with heanet as i cannot, again, ping anything from inside the tunnel and attempts from outside also fail with the following message (from http://www.berkom.blazing.de/tools/ping.cgi).

looking at the routing statistics it would appear that tunnel jumped to life again on the 19th (when you performed your test) and died again on the 24th for still unknown reason.
any advise / direction appreciated.
