[Serusers] mediaproxy functions client_nat_test()

[proson cheng]

Hello all,

I asked the questions but i still don't find an appropiate answer, in 
the fuctions.


client_nat_test("3");
it takes an argument
usually, i see a "3" for the arguments.

what does that 3 mean? does it represent a type of NAT? If so, what 
others argument can I take?

thanks proson
