Hi all

I need to use a tcp proxy with linux ( I prefer but if windows can do =
it
better, why not...) and I would like to know if iptables can do it and =
if
someone already did it (and of course, how) ?
just for information this computer is not a gateway for evereyone on =
our
network but just a computer that help me to bounce on another computer =
for
special security application. I just need to authenticate source IP =
address
and destination port to do the work.
I thought about iptables and PREROUTING but it does not work beceause =
like I
said before, the linux computer have to be the final destination for =
the
Lambda users( and these last have not to know where they take ressource =
in
fact)
