[TriLUG] configuring Linux with my new router

I am stuck on getting my RedHat 7.3 configured with a fixed IP address
so that it can connect to the Internet through my new router (a
Linksys Cable/DSL Router with 4-port switch).
Here is the /etc/sysconfig/network-scripts/ifcfg-eth0 which I am
attempting to use:
When I use the above ifcfg-eth0 file I am able to reach my Windows
machine at 192.168.1.2 (it is also plugged into the router) and I can
ping the router at 192.168.1.1. But an attempt to ping an outside IP
address gets me this error:
connect: Network is unreachable
Each time I change ifcfg-eth0 to try some new idea, I run
to commit the changes.
So what am I doing wrong here?
Is there documentation somewhere on the language used in ifcfg-eth0?
on what the options there are, and what they mean?
For what it is worth, I can get it working if I use dhcp, with the
following as my ifcfg-eth0:
If I use that then the router gives my Linux box an IP address and I
can get out to the Internet. However I do not want to work this way
if I can avoid it because I believe having a preassigned local IP
address will make it easier for me to configure packet forwarding from
Also, for what it is worth, I have been able to set up my Windows
machine with a static IP address working through this router. So it
looks to me like it should be possible.
