Pitspotter ? Isn't that an InSim application ? You don't need a outgaugegateway to combine insim and outgauge application... It is only for outgauge only applications.
OutgaugeGateway is a generic UDP packet forwarder and duplicator. All it does, is listen on one port (first argument in command line) and send the packets it receives to other ports (next arguments in command line). It doesn't send anything back to LFS (if it does, you configured ports incorrectly).
Is there any more outgauge applications i can test this on ? I don't have momo so momoleds probably won't work for me... will use a search button...
