The conf/make-ip-conf.pl script will generate a usable, user-level router 
configuration with a minimum amount of editing; simply replace the Ethernet 
and IP addresses with your own in the $ifs list.

I'm not sure what you mean by testing without the other machines. You can set 
up a variety of fake packet sources (see the documentation for the *Source 
elements) within the configuration, but I think by far the easiest way to 
test your configuration is by actually running it, sprinkling Print elements 
in key places, and running tcpdump while Click is running.
