As a proof of concept..
last year someone argue with me about the port forwarding…
Somehow I don’t agree with the definition of port forwarding given by him..
he completely underestimate what is the port forwarding actually can be
exploited in many thing..
for him.. the port forwarding is nothing much for networking security..
anyhow this proof that there is something really bad or good can be done
by using the port forwarding technique.. In real life..
I do using it a lot.. whenever have to deal with a remote site..
I think I have produced a readme / tutorial regarding this somewhere in June 2006..
