Cannot ping the gateway

Question

Hi
Network:
One firewall where the IP address is the gateway for all the internal computers and server
From one if the internal computers I can ping the the gateway
From the server I can ping all the internal computers but I cannot ping the gateway
On the server I can ping:

I can ping every computer on internal network without any problems, it is only the gateway I have problem with.
