It's easy to reverse the connections during manufacturing, so I wouldn't be confident in any answer you get from another owner, or from the factory.
Set up your satellite equipment by first running the coax through a window to the receiver. Once you get it working, connect the coax to one of the outside ports, and use one of the inside ports for a test. If it doesn't work, go through all 4 possible connections to find the right ones.
If none work, it may take some inspection of the coax for loose connectors, or strands of ground wire shorting to the center pin.
