Ricardo, Actually, if you are having the problem with your ISP, I suspect a large number of technical and non-technical people on the same ISP are having timeout problems with other operating systems and applications. The difference is that you are a knowledgeable user that has identified and knows how to solve the problem. E-mail me directly with the ISP name and I would be willing to contact them about the problem. Actually my studies show that 75% of device on the internet today have or could have IPv6 enabled. I was only sharing the 'conservative numbers'. The biggest jump in IPv6 users in the last 12 months was due to BitTorrent clients on windows system enabling IPv6 tunneling (Teredo). Over the next 4 years, all of the major ISP's are expected to move quickly to dual stack and IPv4 over IPv6 transport. Comcast should be the first, followed the the crowd of cable provides then telcom providers. So 0.1% might be small today, but should get to +1% by the end of 2010. Again on the security side, there are many attacks which have been and are accruing on unsuspecting networks which have IPv6 enable but do not have proper IPv6 security controls (IPv6 capable firewalls, routers, IDS,...). The first attack was back in 2002 on a debian distro that did not have IPv6 firewall enabled, but did have the IPv4 enabled. So continue to believe there are no IPv6 security attacks, the same way as many people said back in 2002, there are no wifi attacks and WEP is secure! BTW, I am not having the problem, I loaded Miredo on my Ubuntu system and it seem to be fine. With that in mind, have we considered just having Miredo installed by default on the Distro?
