IPv6 Tunnel Problem - Debian
![[de]](/s/countries/de.gif) Carmen Sandiego on Thursday, 22 April 2004 13:23:00
Hello,
I have a problem, my internal IPv6 works fine but when i want go out to the Internet i got "no route to host".
Where is the fault? I suggest the Router or Hearbeat Software with wrong Time.
My system:
Debian 3.0 Woody/Sid (pinning)
100 Mbits Ipv4+Ipv6
its behind a router, i think a NAT router.
Ifconfig says:
sixxs Link encap:IPv6-in-IPv4
inet6 addr: 2001:6f8:900:1f9::2/64 Scope:Global
inet6 addr: fe80::c0a8:4/64 Scope:Link
UP POINTOPOINT RUNNING NOARP MTU:1280 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:1316 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:163136 (159.3 KiB)
and the Time (synced with ntpdate ntp0.fau.de):
22 Apr 12:10:58 ntpdate[17889]: step time server 131.188.3.220 offset -3.799100 sec (wrong timezone?!)
Any suggestions? BTW I live in Germany Timezone is set to CEST

Tripple post ;)
Anyhow... check your routing tables as the error is returned from ::1 (localhost).

Wow neat 2 default routes one going into oblivion and also with a lower metric...
Though the 2000::/3 should precede it and be used.
Fix those, check your firewalling rules and then start tcpdumping to figure out what is going wrong.

Sorry i dont know how to "modify" the routing tables, can you give me the commands to delete all needless routes and add the routes that i need.
When i run tcpdump i always get the TCP Packages from my ssh connection (a lot) because im connecting from outside to this box.
DMZ is enabled for this box :O
