Traceroute -6 - Operation not permitted

[Vahis]

OpenSUSE 11.4

Traceroute -6 works fine on one 11.4 machine.
On another one -6 fails, -4 works:

***********************************************
traceroute -6 www.suse.com
traceroute to www.suse.com (2600:806:310::104), 30 hops max, 40 byte
packets using UDP
send failed: Operation not permitted
1 2002:5872:d055::1 (2002:5872:d055::1) 0.000 mssend failed:
Operation not permitted
0.000 mssend failed: Operation not permitted
0.000 ms
***********************************************

Since I'm sure I've done something wrong somewhere I'm wondering which
file(s) could cause this. I can compare stuff with the working machine
but I don't know where to look.

Firewall (the default Suse one) is running on the working machine.
On the non working one turning it of doesn't help.

Second item, same origin, I'm sure

ssh goes both ways between these machines but ssh -6 goes only one way,
_from_ the problematic one to the good one

For ssh -6 I take both firewalls down, haven't figured yet how to pass
IPv6 through, ssh or http.

Traceroute -6 works fine on one 11.4 machine.

Just for info: This is what I get. I have no IPv6 active. I do not think
my router is able to handle it. I have no tunnel and I am not even sure
my provider is able to do it:

***@penne : traceroute -6 www.suse.com
traceroute to www.suse.com (2600:806:310::104), 30 hops max, 40 byte
packets using UDP
Unable to connect to 2600:806:310::104: Network is unreachable

I have zero experience with IPv6, so I have no idea what might cause it.

I have a standard 12.1 with IPv6 on for other reasons. When I look at
the error you get, it looks like it happens after the first hop.

I'm doing this over a tunnel.
It works on other machines but not in one.
I can ping6 it though.

That's because you have no external IPv6.

It does not hop at all. It can't send anything.
Here's the expected output:
