No IPv6 traffic

[Clodoaldo Pinto Neto]

When capturing the traffic with Wireshark there is no IPv6 traffic at
all. When I set network.dns.disableIPv6 to true I can see all IPv4 in
Wireshark. This is Fedora 10 64.

While it is easy to solve it for Firefox there are many services that
can't connect even if I disable IPv6 in the system. One symptom is Yum
has to try repetitively until it finds a suitable host:

http://mirrors.ucr.ac.cr/fedora/releases/10/Everything/x86_64/os/repodata/repomd.xml:
[Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Trying other mirror.

Another is that the weather applet and folding at home can't connect.
When I disable IPv6 in the system the applet connects but Yum behaves
the same (multiple tries) and still folding at home can't connect.

My name servers are set to opendns:

I have another machine, F11, behind the same ADSL router, Dlink DSL
500B, without problems.

Any ideas?
