   james howard and mike higashi got things working 
for us wrt ip addresses, though we can't yet resolve 
domain names from 192.168.173.0 . 
   as to using the Dell switch, the outer-most port 
seems to have been managed for some non-172.30.0.0 
thing. we used a different port (17, i think) and hey, 
now we can get packets out (gotta figure out dns 
resolution, but that'll be next week). 

   the linksys is 172.30.0.34 <--------------------

   (sorry for unnecessary noise: i just found some 
ip address info, james is editing the wiki to note 
the linksys ip address.)
