Julius,
Some background: the university sets the IP protocol like this -- 
10.{building#}.{floor}.{machine}, which is nice.  I don't understand, 
however, why they insist on having the gateway, dns, and proxy on the 
true IPs (202.29.26.1-5 are the proxies), and won't alias them or 
something.  I also don't understand why windows doesn't have a problem 
with this, even though the IP is 10.2.2.1 netmask 255.0.0.0.  If anyone 
can answer that one for me...
I'm the one that has a real problem with the lack of something between 
us and the rest of the university.  If I'm feeling generous, I say I 
don't want to pollute the netwok with our Xserver traffic, although 
netbooting from downstairs  or the listening lab is nice for me.  If I'm 
in a bad mood, however, it is because the entire university is 
unlicensed Win98 machines rife with Nimbda et.al.  It's like Soi Cowboy* 
out there, and I don't need the lists of banned IPs every day in my 
server logs. We get about 10kb/sec of portscans right now, per machine. 
 I don't want that pollution in my lab, either.
I take it, then, that route is my friend, and not my ignorant hack?  I 
was going to use BBIagent as the router, but I don't think I can use 
route with it now.  Any suggestions for the  4 year newbies out here?
Dan
