OMG it is working!!!!!
never thought it would ever be going to happen...
THANKS! you ve made my month!
(lol, did not even think, that i was that close...)

i just added the passwd option, it worked pretty well.
connectivity works fine, but i am just using it for some minutes.
(atm i am using my unis vpn!).

EDIT
i ve tested more and it still works good.
i had one problem when the connection was a bit strange, but a reboot did it; besides that, i haven't spotted any errors.
