Can't see ADSL modem

[Timothy Murphy]

I have a small mystery on my home network.
The machines on the network all run Fedora-16 or CentOS.
All the machines except one, running CentOS-6.2,
can ping the ADSL modem at 192.168.1.254 .

The CentOS-6.2 machine does not get any response to pings
from the modem, but is able to ping sites beyond the modem.

Could some knowledgeable soul suggest a reason for this?
