Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

It's how you setup the firewall, if you can ping other machines, then you have a valid IP, the 127.0.0.1 is a loopback address.
Try ifconfig from the command line, and it should show 2 (or more) intrefaces lo & eth0, eth0 is what you should look at.
I have't configured a router, and don't know where to start.
It looks like a firewall issue, the machine can ping others but other can't ping it.
It could be simply a setting that rifuses a ping request, there 2 ways to resolve the this,
1) throu the firewall program.
2) using ip chains (it's the same as 1, but using text comands instead of a gui)
If you installed an aditional firewall on you system, just do the following.
in a terminal type
ps -ax |more *and find the firewall program that is runing and it's PID*
Kill -9 PID *the PID the number you got using the first command*
If you are using the standard firewall that came w/ RH
In the (start) menu, under services, or network, you should find the firewall program/configurator, from there you can disable, lower or increase the firewall protection and enable what it accepts or not (i.e. HTTP, FTP, ...etc)
