I don't want to admit that on this list ;-)

It appears to if the IP assignment on the cable end is dynamic.  I tried 
it (fixed addresses of the 10.mumble variety) on my powerbook (with 
dynamic addressing at the front end) downstream of the Airport Extreme 
box and the Airport Administration Tool told me that I had to set a 
static address at the front end.  But you must remember that I am 
totally network stupid so it could just be pilot error.  The 
documentation @ Apple on setting up Airport networks is pretty complete 
so I expect this is in there somewhere.
