 when you start orbiter, it opens a port with UPNP. when you close orbiter, it closes the port. no hassle of router configurations necessary. just open with Orbiter.bat and enjoy playing with your friends on OMP
How to Install:
unzip the contents of this zip file into the main directory of orbiter... thats it, nothing more nothing less.
Â
System Requirements:
an orbiter installation with OMP installed (it works without OMP, but its pretty useless)
a router with UPNP enabled (most routers have it enabled streight out of the box)
