Problem getting tunnel online

Hi,
I'm having some problem getting my static tunnel online. I'm terminating the tunnel in a Cisco-router.
Here's parts of the 'sh run':
ipv6 unicast-routing
!
interface Tunnel1
description IPv6 uplink to SixXS
no ip address
ipv6 address 2001:16D8:EE00:BC::2/64
ipv6 enable
ipv6 mtu 1280
tunnel source Dialer1
tunnel destination 83.140.3.18
tunnel mode ipv6ip
end
I can ping6 my local interface (d'uh!), but not the endpoint. From external sources, I can't ping6 the tunnel-address.
Any ideas what I've done wrong?

Hello there
I am facing exactly same problem with same configuration.
I am looking into it, but if you made it work can you let me know what was the fault on your case?
thanks!

Should the tunnel source be Dialer1? Is that not for PPP connections? A static tunnel is straight 6in4 forwarding I think. An example I found online use tunnel source Loopback0, but I haven't done tunneling on a Cisco device.

I solved the problem in my case - I am not sure if it is the same but here it goes:
The issue was that my router which acts also as my ipv4 gateway, is also NATting my LAN to the internet.
That was creating a problem on any kind of connections terminating to my router from the internet.
simply put by removing the 'ip nat outside' statement from the outside interface the ipv6 tunnel worked. My final solution included filtering out gre tunnel traffic from my nat list, and natting the rest.
good luck!
