The problem is:
I can ping the Centos machine from the XP machine. However, when I try
to ping XP from Centos, the ping request arrives at the XP machine but
no reply arrives back at the Centos machine.

I would appreciate some help with this.

If you can ping Centos from the XP machine, then your cabling and IP
routing is OK. Your XP machine is probably configured somewhere not to
respond to pings; there is no doubt a way of changing the configuration
but I don't know that much about them.

Thanks to all of you for the replies. I finally discovered what the
problem was. The Checkpoint VPN software on the XP machine was
blocking ICMP requests. Even when I disabled the VPN it still
continued blocking the ICMP's. I couldn't find any configuration
settings to change this. Uninstalling the VPN solved the problem.
