Ticket ID: SIXXS #991094 Ticket Status: User PoP: deham01 - Easynet (Hamburg)
No packets anymore routed into my established tunnel
![[de]](/s/countries/de.gif) Shadow Hawkins on Wednesday, 04 March 2009 19:21:31
Hi,
My tunnel T14069 (type AYIYA, POP deham01) did work fine for many months.
Since yesterday evening, my tunnel endpoint 2001:6f8:900:acf::2 does
not receive Packets from the tunnel and Sixxs reports a packet loss of
100% too.
The tunnel information says:
IPv6 Prefix 2001:6f8:900:acf::1/64
PoP IPv6 2001:6f8:900:acf::1
Your IPv6 2001:6f8:900:acf::2
Created 2008-01-28 20:18:19 CET
Last Alive 2009-03-03 18:43:53 CET
ping6 to 2001:6f8:900:acf::1 receives no answer. tcpdump on the
ipv6-interface and on the underlying ipv4-interface prints the outgoing
packets, but no reply packets.
Stopping the tunnel with "aiccu stop" and starting with "aiccu start"
was successful, but there is still no traffic coming in. "aiccu test"
reports Userstate: enabled.
The Ping through an other (working) tunnel hosted too by deham01 wrote:
PING 2001:6f8:900:acf::2(2001:6f8:900:acf::2) 56 data bytes
From 2001:6f8:900:a27::1 icmp_seq=1 Destination unreachable: No route
From 2001:6f8:900:a27::1 icmp_seq=2 Destination unreachable: No route
The tunnel endpoint resides inside a private network which is connected
via a NAT-Router (dynamic IPv4 adr's) to the internet. At the critical
time there was no reconnect and no change of the IPv4 address.
Thanks in advance
Andreas

Thanks Jeroen for the fast reply.
I already read the section. Unfortunly I have no cut&pate-capable access to the system while the tunnel is broken; only a KVM-like access.
I just tried to post a lot of related information, but it seems to be lost because it took more time than the login-timeout permitted. Please stand by,
until I hopefully could recover it.

Danke! Thanks!
Whoever may have repaired the item, the tunnel works again.
You may close the ticket as resolved.
