Re: IPv6 Home Use to stimulate deployment over IPv4-NAT
Hi Carlos,
As you can imagine, I did a tunnel only because the native IPv6 was not working for me. I learn, as a first lesson, to see if there
is a RA in the network before I do my own one !
I even asked, and they told me that ONLY v4 was available in that network.
In fact I show to some people from the organization that curiously, v4 was not working also. I got an address assigned by DHCP, but
no way to use web or pop3/smtp. Some other people experienced the same problem, so I guess it wasn't my own computer.
So I tried my own tunnel, and it worked. If you filter port 41, that's still fine for me (unless you mean proto-41).
Obviously the round-trip was not good, but it was due to the network configuration itself, as I was doing a ping to my tunnel end.
If I ping with v4, the round trip must be almost the same !
Anyway, I tried to show that even when IPv4 is not working, I can use IPv6, and that's was a real situation ... I prefer to have a
slower connectivity that _nothing_.
Clearly we must improve this, but this is what we are working now, here in this group.
I prefer to show the people the true, not just telling them everything is wonderful and we have nothing to do. I'm sure other people
is in the same side.
Regards,
Jordi
