Cannot ping other computers on LAN

It seems this question has been asked many times before but I can't seem to
find the solution from the responces so I apoligize in advance.

I can access the internet fine on both computers. I can use the IPX protocol
successfully between both computers when playing games. However ping does
not work. I discovered this trying to set up ssh.

I have a Mandrake 9.1 and here is my LAN setup:

DSL MODEM
|
V
ROUTER/SWITCH
192.168.2.1 --> Computer A 192.168.2.2
|
|
V
Computer B
192.168.2.3


When I ping from Computer A to B or B to A ping never gets a responce back:
(All commands from Computer A)

[charlie@localhost charlie]$ ping -c 1 192.168.2.3
PING 192.168.2.3 (192.168.2.3) 56(84) bytes of data.

Can someone help me to find out what I need to do to fix this please?

Thanks in advance,
Charlie
