Thats not a subnet mask. It is actually a wild card mask. Saying anything
more will just be giving away the solution prior to everyone getting a
chance.

Hey Group,
To take a shot at this question: John, I think the answer is
different... I'm not exactly sure how this is done, but by your model I'm
imagining that you have the subnet mask as 0.0.0.24 so that you can get all
of the required numbers to be excepted. Actually I think the subnet mask
should be 0.0.0.25.
Because it lays out like this: (yours): 0.0.0.00011000, if you do it like
this than the addresses bit places would not match up with the net mask.
(with mine):
0.0.0.00011001, all of the addresses specified (.1, .9, .17, and .25) all
will match up with the mask and be allowed through...I think ;) Don't get me
wrong, you may be right and I could just be rambling without a cause here ;)
After all, I'm just a rookie ;) Let me know if I'm wrong and I'm gonna stay
tuned to find out the answer. I've probably got something wrong with the IP
address part...oh well, I'm waiting ;)

If I'm correct, I'll post how I did it later...right now I'm still
wondering... :-)
Chuck, you're mean...just plain mean!
Good luck all!
