The following is the output of 'ifconfig -a'.

And here is the 'tcpdump -i he-ipv6 ip6' record when I ping6 to the server side of the tunnel:

Code:

14:32:23.731075 IP6 yang0914-1-pt.tunnel.tserv22.tyo1.ipv6.he.net > yang0914-1.tunnel.tserv22.tyo1.ipv6.he.net: ICMP6, echo request, seq 3, length 64

Because someone else has done this before ...

I can ping the IPv4 address of the remote tunnel end point, but not work with the IPv6 address.
And my router can forward the proto41 packets.   

Hi, all:
I have created a ipv6 tunnel on a Fedora server with the following commands:

Code:

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 74.82.46.6 local 10.21.0.8 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:23:5d8::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6

I use the private IP address(10.21.0. instead of my public address(114.xx.xx.xx)
But when I finish all the steps and ping6 a ipv6 address like 2001:470:23:5d8::1 or www.kame.net,
The response will always show "Destination unreachable: Address unreachable"

Could someone tell me where I have gone wrong?
Thanks.
