This does not work, unless I am missing something. This only changes the port at which the MT unit listens on for http traffic.
I need to change the actual port that WinBox uses. i.e. from 8291 to 1024
In this way I could set my port foward up.
Winbox uses 1024 to connect - I foward port 1024 in my modem to the IP of my MT box at 188.8.131.52 to port 8291
