I have not been able to render over the internet using Lightning. Furthermore, I can only get Lightning to work on two of three "local network" computers even though the icons for the other two are "green" in network manager which means communication has been established. Further furthermore, I can't get tiling to network render a single frame. I have zone alarm set to accept the other IP's. I'm posting this because I just read ddaydreams say this should all be possible. Has anyone acually rendered over the internet using Lightning?
