Hi all,
seems my v6 tunnel is no longer working.
tserv1 sends me an ICMP port unreachable.
Provider is Deutsche Telekom, OS is Linux. This tunnel was working before.
# tcpdump -n -i ppp0 host 216.66.80.30
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ppp0, link-type LINUX_SLL (Linux cooked), capture size 65535 bytes
16:51:49.297381 IP 216.66.80.30 > 93.200.118.57: ICMP 216.66.80.30 protocol 41 port 0 unreachable, length 132

I did that 7½ hours ago.

I did not get any ICMP errors from the tunnel server at the time. But AFAIK during a tunnel server restart all users will get those ICMP errors. And at the moment the connection appears to be working again:

This is however a reoccurring problem. I only keep using tserv1.fra because it gives me opportunity to test how my gateway deals with a failing tunnel server, and automatically finds alternatives. I think the other tunnel servers are much more reliable.
