well am afraid that ipv6 address never is going to be reachable from outside , besides i am the only one here working with ipv6

i have here a private ipv6 address i think thats wrong because someday ipv6 must be reachable , my idea was have a real ipv6 addres , but im not that powerfull to do that and my provider also does not support ipv6 in his backbond :-)

anyway what i was going.

let me show ya an example .

ping6 intranet.cnt.uo.edu.cu
D:\Documents and Settings\Administrador>ping6 intranet.mydomain.cu

Haciendo ping intranet.mydomain.cu [2001:b00:f80e:6c00::1]
de 2001:b00:f80e:6c00::3 con 32 bytes de datos:

Respuesta desde 2001:b00:f80e:6c00::1: bytes=32 tiempo<1m
Respuesta desde 2001:b00:f80e:6c00::1: bytes=32 tiempo<1m

D:\Documents and Settings\Administrador>tracert intranet.mydomaincu

Traza a la dirección intranet.mydomain.cu [2001:b00:f80e:6c00::1]
sobre un máximo de 30 saltos:

  1    <1 ms    <1 ms    <1 ms  2001:b00:f80e:6c00::1


also telnet to same address on port 25
220 cnt.uo.edu.cu ESMTP Postfix (Debian/GNU)

, but when i try to connect my email client
to the email server windows  cpu get 100%

and of course never download the email :)
he just stay loading..........
instead linux computers everything work ok

heheheeh
everyday i hate more windows LOL


ahh
other detail
i have radvd runing ,as the routing is working ok because i have ipv6 conettivity to ther ipv6 networks  .
