i don''t know, but it is not... hmmm
i am damned anyway, as there is no way to solve my problem. HTB is not going to
help me, all this linux''s TC is not going to help me.. me? why me?
there are many people fighting with that problem, so this is also their defeat
:-(

101% right. no way to deal with them.

Thank you all for your time!
I do really appreciate your engage in my problem.
There is no linux without guys like you all here :-)

The pleasure is mine :-)

There is MLDonkey running on that and it is also Internet default gateway for my
