Anybody knows how can I drop pings from outside my MT to inside ? so I want to do pings from inside MT to outside.

i.e. my eth0 ip address is 192.168.0.54 and my gateway is 192.168.0.1
I want to ping from 192.168.0.54 to 192.168.0.1 but I want disable ping from 192.168.0.1 to 192.168.0.54

as simple as that
