However, you can get a /48 prefix from Hurricane Electric for free, 6in4 tunneling requires direct Internet connection (or at least ability to forward incoming traffic to your endpoint) and so is out of question for many (if not most) users. I don't quite follow this.
I suppose that if I browse the web via this tunnel, the replies will automatically go back via the same tunnel, no problem there.
The problem would be if some one tries to contact me on IPv6: Hurricane (or other) has to open a connection to my IPv4 address via the tunnel. I don't see the problem there, as long as the tunnel is connected at both ends.
Or is it something else? :-?
I think he was referring to the fact that some people are behind carrier grade NAT, which means they don't have any public IPv4 address and so have nothing for the tunnel to connect to. 6in4 use IP protocol 41 and you have to provide a valid IPv4 address for those packets to be sent to. You can't do that, if your ISP uses NAT. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
