The 10.1.1.1 gateway specified is actually our firewall on that network which
gets us out to the internet.  If specifying that causes a problem, I can
remove it, because the 192.168.0.0 clients do not need to get to the
internet.  They only need access to the 10.1.1.0 network.

I tried setting the gateway in /etc/sysconfig/network and
/etc/sysconfig/static-routes to 10.1.1.100 which is the router I set up, and
unfortunately I still can't route traffic from 192.168.0.0 to 10.1.1.0.

Thanks,
