Dimitri, do you consider NOT port forwarding as essential?  It appears that JK has gone to the trouble of advising port forwarding, and creating an interface to specify parameters and advise users on Port Forwarding setup.  I haven't found that Port Forwarding makes any difference, but I'd like to know, technically, why you strongly advise against it.  Just trying to understand the reasoning behind it.  Thanks!
