If you actually open ports up for some services on the router, a firewall on 
your machine can provide an extra layer of protection to stop intruders from 
taking advantage of the open port.  If you want to actually see logs from 
your router/firewall, I think that you are stuck, it won't write those to a 
disk, that I know of, and if it did it probably wouldn't do that to a Linux 
formatted disk.  

Personally, I would not put my machine in the DMZ and remove one great layer 
of protection just to be able to see logs of people turned away, YMMV.  I 
have installed and played around with a lot of intrustion detection software 
and stuff like portsentry which is pretty useless if you use a hardware 
firewall like a router, but if you were paranoid, you could use both to 
provide that extra layer of security.
