The way it is worded, I can see either interpretation: that the default should always be 9180, or, only that that 9180 has to be supported. Regardless, lots of networks are set at 4470, so, pragmatically, 4470 is probably a good compromise. How much performance difference do you see between 4470 and 9180? -- Hugh LaMaster, M/S 233-21, Email: lamaster@nren.nasa.gov NASA Ames Research Center Or: lamaster@nas.nasa.gov Moffett Field, CA 94035-1000 Or: lamaster@george.arc.nasa.gov Phone: 650/604-1056 Disc: Unofficial, personal *opinion*.
