Thank you very much for the solution, but I still have a problem and I
need help :) . The problem number one has been solved. When I trace from
any computer of my LAN, It`s go out from the right ISP. But after a short
time, is like if the rute was chached and it back to the same problem.
(I´m getting paranoic :-P )

The Problem number two still happens when someone from outside trace an IP
from mi LAN. Always the before complete jump is responded for the
interface who correnspond to the other ISP.

Do you have an idea what can be the failure... or, can I call this a
failure in my config?

THANKS VERY MUCH
