Hmmm... I've never heard of "security" by limiting the available IP
addresses ... so there MUST be a fatal flaw in my argument ... but here it
is...

a. Assume the "bad guys" CAN change their IP address (a la John Navas'
suggestion) ... but also assume the following conditions ...

b. The Wireless router is assigned to an "arbitrary" range, say the 3 IP
addresses can be assigned to a limited contiguopus range that the "bad
guys" don't (yet) know (e.g., 192.168.145.128 to 192.168.145.120).

c. Assume that all three PCs are on the network so there are now zero
available IP addresses.

My security question:
How can the bad guy get in given those three assumptions above?

If we can't figure out how (and of course, if we can't do it ourselves),
then we've just uncovered an heretofore unknown wireless security method
that has never before been seen in print!
