Well, smack me, and call me an idiot, I'm not thinking clearly it
seems. The problem is right there in front of me, and my previous
message even points it out implicitly. You need to specify the subnet
in your dhcp config as 192.168.0.0, and not as 192.168.1.1. A subnet
of 192.168.1.1, and netmask of 255.255.255.0 are indeed an incorrect
combination. You would then define your router as 192.168.1.1 via the
routers option inside the 192.168.0.0 subnet like so:

option routers 192.168.1.1;

So, try that before sending us your config file, since chances are
very good that you won't have to. Sorry for the confusion, my mind
really is somewhere else today I guess.
