Re: IPv6 Home Use to stimulate deployment over IPv4-NAT
Carlos,
As I explained there, I can use v4 with some protocols and destinations, may be it was a combination of firewall/filter+routing
problem, not sure, but for sure I was able to bring up the tunnel and then I started to work almost normally (but with v6), I even
gained access to our streaming server, under test.
It was also pity for me not being able to show the Isabel application, but as you know the people that setup it, had only a couple
of days to try to sort out all the problems, and it was impossible to setup it w/o disturbing the running sessions, connecting 25
sites across the world (they worked perfectly). Next time !
Regards,
Jordi
