Problem with heartbeat tunnel
![[fi]](/s/countries/fi.gif) Shadow Hawkins on Saturday, 17 July 2004 10:34:22
When I am pinging POP IPv6 (ping6 2001:14b8:100:10::1):
PING 2001:14b8:100:10::1(2001:14b8:100:10::1) 56 data bytes
From ::1 icmp_seq=2 Destination unreachable: Address unreachable
From ::1 icmp_seq=3 Destination unreachable: Address unreachable
Tcpdump shows:
11:03:55.510972 IP dsl-lprgw4mdf.dial.inet.fi > sixxs-gw.kv9.net: cl-17.hel-01.fi.sixxs.net > gw-17.hel-01.fi.sixxs.net: icmp6: echo request seq 3
11:03:55.762686 IP sixxs-gw.kv9.net > dsl-lprgw4mdf.dial.inet.fi: icmp 132: sixxs-gw.kv9.net protocol 41 unreachable
11:03:56.512591 IP dsl-lprgw4mdf.dial.inet.fi > sixxs-gw.kv9.net: cl-17.hel-01.fi.sixxs.net > gw-17.hel-01.fi.sixxs.net: icmp6: echo request seq 4
11:03:56.884038 IP sixxs-gw.kv9.net > dsl-lprgw4mdf.dial.inet.fi: icmp 132: sixxs-gw.kv9.net protocol 41 unreachable
Pinging my own IPv6 works:
PING 2001:14b8:100:10::2(2001:14b8:100:10::2) 56 data bytes
64 bytes from 2001:14b8:100:10::2: icmp_seq=1 ttl=64 time=0.242 ms
64 bytes from 2001:14b8:100:10::2: icmp_seq=2 ttl=64 time=0.185 ms
Tunnel was static before and fully working then my ISP changed something and my IP started to change at every reboot. I requested change: static tunnel to heartbeat and got it, but havent got it working anymore.
Tunnel state is 'User disabled' and I can't find [enable] button anymore on the page. Should tunnel state change automatically to 'Enabled' when tunnel is working?
I am using Debian linux and I dont have any firewalls or NAT systems.
