[LARTC] wondershaper and dmzs

[seph <seph@directionless.org>]

I have a pretty simple setup. I've got a linux nat box, with some
internal hosts. I've also got some servers in a dmz. It looks
something like this:

               Internet 
                  |    
           (external network)             
             |           |   
             |           |   
           linux        dmz 
            nat        hosts
             |            
             |         
       (office network)  
             |           
             |           
           office  
            hosts  

I'd like to shape the office traffic that's going out to the internet,
while leaving the office traffic to the dmz alone. After all, the
network link the dmz fast. I've been using wondershaper, since it's
easy and works well, but I'm not sure how to add in an exception for
the dmz hosts.

Can I do this with tc, or is the entire interface shaped? It seems
like I might be able to create a more explicate filter, but I'm having
trouble getting it to work.
