+       REMOTE_PORT is the port that you'll get on the proxy server, any number over 1000 works as long as you and your techy plug in the same number. This number gets used as a kind of identifier for your remote support session.
+       USER is just your username at the remote proxy machine, if left blank it is assumed to be the same as your username on your local machine
