I cant be the first one to ask this... Am I?
Is there a way to share internet connection to a device from airport to ethernet in 10.6.8 Server?
Sure - in Server Admin you get to choose which network connection you're sharing (AirPort) to clients on which network (ethernet). I don't recall the specifics (I don't have a 10.6 server handy), but it's entirely possible.
