I have a front end on a laptop which is connected via hardwire and  
wireless, depending on where I am sitting. I keep those two mediums  
as separate networks because I treat the wireless a little  
differently in terms of security.

That's kind of what I thought, just wasn't sure if there was any  
other way. Kinda like with the mysql database - if you  specify which  
interface you want to listen on, you can only give it one interface,  
otherwise, you just let it listen on all (in the mysql config) and  
have to block the ones you don't want it listening on via the  
firewall... Thanks for the help. -m
