Hi,
I setup a tunnel as I read. The tunnel up and running but IPv6 traffic doesn't work. :-(
My network:
My home network is connected to Tkom telco by ONT device.
The router is terminating the PPPoE connection on my OpenWRT router.
There is a global IPv6 address from the telco. It is just an IPv6 address not a prefix. (I'm not sure ...) I think it is working bacause if I use "ping -I pppoe-Tkom ipv6.google.com" ping is working. Without -I interface parameter no answer.
Of course 6in4-henet interface is up:
root@DHGLr:~# ifconfig
6in4-henet Link encap:IPv6-in-IPv4
inet6 addr: fe80::c0a8:140/64 Scope:Link
inet6 addr: <IPv6-my-tunnel-ed>::2/128 Scope:Global
UP POINTOPOINT RUNNING NOARP MTU:1280 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:4689 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1
RX bytes:0 (0.0 B) TX bytes:375088 (366.2 KiB)
As you can see RX is 0!!! So no received packets! :-(
Here is my routing table:

I think as you can see I'm not an IPv6 expert - yet! :-) So please tell me exact ifconfig or route commands. I know those commands with IPv4 but not with IPv6!
Of course I can give more information if it needs.
And if you think about why I want to use HE.net TLB the answer is: my Telco filter out all IPv6 incoming traffic. So I can use IPv6 from my home network which is directed to the Net and it is filtered out from the Net so I can't reach my home devices or WEB/SSH server. :-(
BTW!
Maybe the ip6tables is wrong, too ...
Thank you for your help in advance!
TIA,
Ruzsi
are there any firewalls on the tunnel that might restrict traffic?
