I was using 0.0.0.0 as the NIM client setup requires I add one in as it's defining a new network.
Do you setup your new NIM network first or as part of the client definition?
My install gets as far as downloading the boot image, but then hangs on the flashing 608 - which is trying to get client info file i think. If I have anything but 0.0.0.0 defined as the gateway it doesn't get past trying to download the boot image.
Thanks,
John
